+# UNO-based Graphics Backend
+
+UNO-based graphics backend, lesser impedance to modern graphics APIs
+than vcl.
+
+## The canvas Framework
+
+The `canvas` framework is the successor of the system GUI and graphics
+backend VCL. Basic functionality is available, supplying just as much
+features as necessary to provide a VCL-equivalent feature set (except
+proper BiDi/CTL support).
+
+The `canvas` framework consists of the following two modules, `canvas` and
+`cppcanvas`. Additionally, a new generic graphics tooling is used (but
+not exclusively by the canvas, Armin's drawinglayer module also make
+use of it), which resides in `basegfx`.
+
+The UNO API used by the canvas is primarily under
+`css::rendering`, with `css::rendering::XCanvas`
+being the central interface.
+
+## The slideshow Engine
+
+The `slideshow` engine has replaced the former Impress-embedded
+presentation framework with a fully independent UNO component, and it
+is based on the canvas. Some features used there are only available
+from `canvas`, like double-buffering, and hardware-accelerated
+alpha-blending (currently not on all platforms).
+
+## Cairo canvas
+
+Cairo `canvas` is one of backends of canvas component. `canvas` is mostly
+used for slideshow rendering and also for emf+ rendering. we hoped it
+will even be used by drawing layer, but it didn't happen (yet?) for
+API look at `offapi/com/sun/star/rendering/`, the implementation is in
+`canvas` and `cppcanvas` modules.
+
+Cairo `canvas` backend uses Cairo library for rendering. Main advantage
+is support of alpha transparency and in some cases accelerated
+rendering.
+
+The backend itself is quite old and stable, not many changes in that
+area lately, mostly changes for emf+ rendering, communication with
+vcl and bugfixes
+
+## Future Works
+
+Look at Cairo `canvas` and situation when it is used
+(mostly slideshow).
+
+## TODO
+There still might be more cases when we
+can save some roundtrips when exchanging data with vcl.

+
+        Use this helper to handle the XCanvas part of your
+        implementation. In theory, we could have provided CanvasHelper
+        and CanvasBase as a single template, but that would duplicate
+        a lot of code now residing in CanvasHelper only.
+
+        This template basically interposes itself between the full
+        interface you implement (i.e. not restricted to XCanvas. The
+        problem with UNO partial interface implementation actually is,
+        that you cannot do it the plain way, since deriving from a
+        common base subclass always introduces the whole set of pure
+        virtuals, that your baseclass helper just overridden) and your
+        implementation class. You then only have to implement the
+        functionality <em>besides</em> XCanvas.
+
+        <pre>
+        Example:
+        typedef ::cppu::WeakComponentImplHelper < css::rendering::XSpriteCanvas,
+                                                  css::lang::XInitialization,
+                                                  css::lang::XServiceInfo,
+                                                  css::lang::XServiceName > CanvasBase_Base;
+        typedef ::canvas::internal::CanvasBase< CanvasBase_Base, CanvasHelper > ExampleCanvas_Base;
+
+        class ExampleCanvas : public ExampleCanvas_Base,
+                              public SpriteSurface,
+                               public RepaintTarget
+        {
+        };
+        </pre>
+
+        @tpl Base
+        Base class to use, most probably the
+        WeakComponentImplHelper template with the appropriate
+        interfaces. At least XCanvas should be among them (why else
+        would you use this template, then?). Base class must have an
+        Base( const Mutex& ) constructor (like the
+        WeakComponentImplHelper template has). As the very least,
+        the base class must be derived from uno::XInterface, as some
+        error reporting mechanisms rely on that.
+
+        @tpl CanvasHelper
+        Canvas helper implementation for the backend in question. This
+        object will be held as a member of this template class, and
+        basically gets forwarded all XCanvas API calls. Furthermore,
+        every time the canvas API semantically changes the content of
+        the canvas, CanvasHelper::modifying() will get called
+        (<em>before</em> the actual modification takes place).
+
+        @tpl Mutex
+        Lock strategy to use. Defaults to using the
+        BaseMutex-provided lock.  Every time one of the methods is
+        entered, an object of type Mutex is created with m_aMutex as
+        the sole parameter, and destroyed again when the method scope
+        is left.
+
+        @tpl UnambiguousBase
+        Optional unambiguous base class for XInterface of Base. It's
+        sometimes necessary to specify this parameter, e.g. if Base
+        derives from multiple UNO interface (were each provides its
+        own version of XInterface, making the conversion ambiguous)

+
+        @tpl Base
+        Base class to use, most probably one of the
+        WeakComponentImplHelperN templates with the appropriate
+        interfaces. At least XCustomSprite and Sprite should be among
+        them (why else would you use this template, then?). Base class
+        must have a Base( const Mutex& ) constructor (like the
+        WeakComponentImplHelperN templates have).
+
+        @tpl SpriteHelper
+        Sprite helper implementation for the backend in question
+
+        @tpl CanvasHelper
+        Canvas helper implementation for the backend in question
+
+        @tpl Mutex
+        Lock strategy to use. Defaults to using the
+        BaseMutex-provided lock.  Every time one of the methods is
+        entered, an object of type Mutex is created with m_aMutex as
+        the sole parameter, and destroyed again when the method scope
+        is left.
+
+        @tpl UnambiguousBase
+        Optional unambiguous base class for XInterface of Base. It's
+        sometimes necessary to specify this parameter, e.g. if Base
+        derives from multiple UNO interface (were each provides its
+        own version of XInterface, making the conversion ambiguous)
+
+        @see CanvasCustomSpriteHelper for further contractual
+        requirements towards the SpriteHelper type, and some examples.

+    /** Helper template base class for XGraphicDevice implementations.
+
+        This base class provides partial implementations of the
+        XGraphicDevice-related interface, such as XColorSpace.
+
+        This template basically interposes itself between the full
+        interface you implement (i.e. not restricted to XGraphicDevice
+        etc.). The problem with UNO partial interface implementation
+        actually is, that you cannot do it the plain way, since
+        deriving from a common base subclass always introduces the
+        whole set of pure virtuals, that your baseclass helper just
+        overridden) and your implementation class. You then only have
+        to implement the functionality <em>besides</em>
+        XGraphicDevice. If you want to support the optional debug
+        XUpdatable interface, also add that to the base classes
+        (client code will call the corresponding update() method,
+        whenever a burst of animations is over).
+
+        <pre>
+        Example:
+        typedef ::cppu::WeakComponentImplHelper < css::rendering::XGraphicDevice,
+                                                  css::rendering::XColorSpace,
+                                                  css::rendering::XPropertySet,
+                                                  css::lang::XServiceInfo,
+                                                  css::lang::XServiceName > GraphicDeviceBase_Base;
+        typedef ::canvas::internal::GraphicDeviceBase< GraphicDeviceBase, DeviceHelper > ExampleDevice_Base;
+
+        class ExampleDevice : public ExampleDevice_Base
+        {
+        };
+        </pre>
+
+        @tpl Base
+        Base class to use, most probably the
+        WeakComponentImplHelper template with the appropriate
+        interfaces. At least XGraphicDevice should be among them (why else
+        would you use this template, then?). Base class must have an
+        Base( const Mutex& ) constructor (like the
+        WeakComponentImplHelper template has). As the very least,
+        the base class must be derived from uno::XInterface, as some
+        error reporting mechanisms rely on that.
+
+        @tpl DeviceHelper
+        Device helper implementation for the backend in question. This
+        object will be held as a member of this template class, and
+        basically gets forwarded all XGraphicDevice API calls that
+        could not be handled generically.
+
+        @tpl Mutex
+        Lock strategy to use. Defaults to using the
+        DisambiguationHelper-provided lock. Every time one of the methods is
+        entered, an object of type Mutex is created with m_aMutex as
+        the sole parameter, and destroyed again when the method scope
+        is left.
+
+        @tpl UnambiguousBase
+        Optional unambiguous base class for XInterface of Base. It's
+        sometimes necessary to specify this parameter, e.g. if Base
+        derives from multiple UNO interface (were each provides its
+        own version of XInterface, making the conversion ambiguous)

+        /** This helper template wraps VCL objects, and protects
+            object deletion with the Solar mutex. All other operations
+            are unprotected, this must be handled by client code.
+
+            The reason for this template is the fact that VCL objects
+            hold by value in uno::Reference-handled classes are
+            deleted without having the chance to get inbetween and
+            lock the solar mutex.
+
+            This template handles that problem transparently, the only
+            inconvenience is the fact that object member access now
+            has to be performed via operator->, since . is not
+            overloadable.
+
+            Otherwise, the template preserves the value semantics of
+            the wrapped object, that is, copy operations are performed
+            not by copying pointers, but by copying the underlying
+            object. This includes constness, i.e. on a const
+            VCLObject, only const methods of the wrapped object can be
+            called. Simply imagine this to be a value object of type
+            "template argument", with the only peculiarity that
+            member/method access is performed by operator-> instead of
+            the non-existing "operator.".

+How to write a canvas test:
+===========================
+
+The easiest (relatively speaking) way is to copy&paste from somewhere. Use existing tests
+as the base, or canvas/workben/canvasdemo.cxx should be a good source too. If that doesn't
+help, then you'll need to find the right UNO interfaces (see canvas/README). Have "fun".
+
+
+Currently only the vclcanvas implementation is tested, because it's the only one
+capable of working with offscreen surfaces. Other implementations would need to
+be fixed, and then added to the gb_CppunitTest_use_components list in the makefile.

+    /* Concepts:
+       =========
+
+       This OpenGL canvas implementation tries to keep all render
+       output as high-level as possible, i.e. geometry data and
+       externally-provided bitmaps. Therefore, calls at the
+       XCanvas-interfaces are not immediately transformed into colored
+       pixel inside some GL buffer, but are retained simply with their
+       call parameters. Only after XSpriteCanvas::updateScreen() has
+       been called, this all gets transferred to the OpenGL subsystem
+       and converted to a visible scene. The big advantage is, this
+       makes sprite modifications practically zero-overhead, and saves
+       a lot on texture memory (compared to the directx canvas, which
+       immediately dumps every render call into a texture).
+
+       The drawback, of course, is that complex images churn a lot of
+       GPU cycles on every re-rendering.
+
+       For the while, I'll be using immediate mode, i.e. transfer data
+       over and over again to the OpenGL subsystem. Alternatively,
+       there are display lists, which at least keep the data on the
+       server, or even better, vertex buffers, which copy geometry
+       data over en bloc.
+
+       Next todo: put polygon geometry into vertex buffer (LRU cache
+       necessary?) - or, rather, buffer objects! prune entries older
+       than one updateScreen() call)

+        anyway). Basically, ::canvas::CanvasCustomSpriteBase should
