+To build and run WebRender in Gecko:
+1. Install Rust if you don't have it already
+ If you are doing gecko builds already, you should already have Rust as it is a build requirement.
+ If not, you can install it using |mach bootstrap| (recommended) or from https://www.rust-lang.org/
+ Note: If installing manually, use the stable 64-bit release - on Windows make sure to use the MSVC ABI installer.
+ Ensure that rustc and cargo are in your $PATH (adding $HOME/.cargo/bin/ should be sufficient)
+2. Build using |mach build|.
+ You don't need anything special in your mozconfig for local builds; webrender will be built by default.
+3. Run with |MOZ_WEBRENDER=1| in your environment. e.g. |MOZ_WEBRENDER=1 ./mach run|.
+ Alternatively, you can set the gfx.webrender.enabled pref to true (browser restart required).
+ Note that on Linux, acceleration is disabled by default and it needs to be enabled for WebRender to work.
+ On Linux you can enable acceleration by putting |MOZ_ACCELERATED=1| in your environment, or setting layers.acceleration.force-enabled to true in about:config.
+4. Verify WebRender is enabled. You can do this by going to about:support and checking the "Compositing" line in the Graphics section. It should say "WebRender".
+ There should also be a WebRender section under "Decision Log" in about:support, which will provide some more detail on what caused it to be enabled/disabled.
+
+When making changes:
+ - Make the changes you want.
+ - Run |mach build| or |mach build binaries| as desired.
+
+For a debug webrender build:
+ Use a debug mozconfig (ac_add_options --enable-debug)
+ You can also use an opt build but make webrender less optimized by putting opt-level=0 in the [profile.release] section of your toolkit/library/rust/Cargo.toml file
+ See also https://groups.google.com/forum/#!topic/mozilla.dev.servo/MbeMcqqO1fs

+/// Merges a new partial blob image into an existing complete one.
+///
+/// A blob image represents a recording of the drawing commands needed to render
+/// (part of) a display list. A partial blob image is a diff between the old display
+/// list and a new one. It contains an entry for every display item in the new list, but
+/// the actual drawing commands are missing for any item that isn't strictly contained
+/// in the dirty rect. This is possible because not being contained in the dirty
+/// rect implies that the item is unchanged between the old and new list, so we can
+/// just grab the drawing commands from the old list.
+///
+/// The dirty rect strictly contains the bounds of every item that has been inserted
+/// into or deleted from the old list to create the new list. (For simplicity
+/// you may think of any other update as deleting and reinserting the item).
+///
+/// Partial blobs are based on gecko's "retained display list" system, and
+/// in particular rely on one key property: if two items have overlapping bounds
+/// and *aren't* contained in the dirty rect, then their relative order in both
+/// the old and new list will not change. This lets us uniquely identify a display
+/// item using only its bounds and relative order in the list.
+///
+/// That is, the first non-dirty item in the new list with bounds (10, 15, 100, 100)
+/// is *also* the first non-dirty item in the old list with those bounds.
+///
+/// Note that *every* item contained inside the dirty rect will be fully recorded in
+/// the new list, even if it is actually unchanged from the old list.
+///
+/// All of this together gives us a fairly simple merging algorithm: all we need
+/// to do is walk through the new (partial) list, determine which of the two lists
+/// has the recording for that item, and copy the recording into the result.
+///
+/// If an item is contained in the dirty rect, then the new list contains the
+/// correct recording for that item, so we always copy it from there. Otherwise, we find
+/// the first not-yet-copied item with those bounds in the old list and copy that.
+/// Any items found in the old list but not the new one can be safely assumed to
+/// have been deleted.
