+Naively, it would be ideal to map directly from ycbcr to rgb,
+but headroom and footroom are problematic: For e.g. narrow-range-8-bit,
+our naive LUT would start at absolute y=0/255. However, values only start
+at y=16/255, and depending on where your first LUT sample is, you might get
+very poor approximations for y=16/255.
+Further, even for full-range-8-bit, y=-0.5 is encoded as 1/255. U and v
+aren't *as* important as y, but we should try be accurate for the min and
+max values. Additionally, it would be embarassing to get whites/greys wrong,
+so preserving u=0.0 should also be a goal.
+Finally, when using non-linear transfer functions, the linear approximation of a
+point between two samples will be fairly inaccurate.
+We preserve min and max by choosing our input range such that min and max are
+the endpoints of their LUT axis.
+We preserve accuracy (at and around) mid by choosing odd sizes for dimentions.
+
+But also, the LUT is surprisingly robust, so check if the simple version works
+before adding complexity!

+// The list of virtual screens is per-NSOpenGLPixelFormat; it is filtered down to only the
+// renderers that support the requirements from the pixel format attributes. Indexes into this
+// list (such as currentVirtualScreen) cannot be used interchangably across different
+// NSOpenGLPixelFormat instances.
+// Display mask: A bitset per GL renderer. Different renderers have disjoint display masks. The
+// Apple software renderer has all bits zeroed. For each CGDirectDisplayID,
+// CGDisplayIDToOpenGLDisplayMask(displayID) returns a single bit in the display mask.
+// CGDirectDisplayID: An ID for each (physical screen, GPU which can drive this screen) pair. The
