+   There are two issues we must contend with when drawing. These are
+   controlled with ROOTLESS_PROTECT_ALPHA and ROOTLESS_ACCEL.
+
+   If ROOTLESS_PROTECT_ALPHA is set, we have to make sure that the alpha
+   channel of the on screen windows is always opaque. fb makes this harder
+   than it would otherwise be by noticing that a planemask of 0x00ffffff
+   includes all bits when depth==24, and so it "optimizes" the planemask to
+   0xffffffff. We work around this by temporarily setting depth=bpp while
+   changing the GC.
+
+   So the normal situation (in 32 bit mode) is that the planemask is
+   0x00ffffff and thus fb leaves the alpha channel alone. The rootless
+   implementation is responsible for setting the alpha channel opaque
+   initially.
+
+   Unfortunately drawing with a planemask that doesn't have all bits set
+   normally causes fb to fall off its fastest paths when blitting and
+   filling.  So we try to recognize when we can relax the planemask back to
+   0xffffffff, and do that for the duration of the drawing operation,
+   setting the alpha channel in fg/bg pixels to opaque at the same time. We
+   can do this when drawing op is GXcopy. We can also do this when copying
+   from another window since its alpha channel must also be opaque.
+
+   The other issue to consider is that the rootless implementation may
+   provide accelerated drawing functions if ROOTLESS_ACCEL is set. For some
+   drawing primitives we swap in rootless acceleration functions, which use
+   the accelerated drawing functions where possible.
+
+   Where both alpha protection and acceleration is used, it is even a bigger
+   win to relax the planemask to all ones because most accelerated drawing
+   functions can only be used in this case. However, even if we can't set
+   the planemask to all ones, we can still use the accelerated
+   CompositePixels function for GXcopy if it is a forward copy. This is
+   mainly intended for copying from pixmaps to windows. The CompositePixels
+   operation used sets alpha to 0xFF during the copy.
+
+   The three macros below are used to implement this, potentially accelerated
+   drawing ops look something like this:
