+/* Our main problem when drawing is that we have to make sure that
+   the alpha channel of the windows we're drawing in 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
+   "optimizes" the pm to 0xffffffff. We work around that by temporarily
+   setting depth=bpp while changing the GC.
+
+   Anyway, so the normal situation (in 32 bit mode) is that the
+   planemask is 0x00ffffff and thus fb leaves the alpha channel alone
+   (and it's opaque initially, so things work out).
+
+   But there's a problem with drawing with a planemask that doesn't
+   have all bits set - it normally causes fb to fall off its fastest
+   paths when blitting and filling.
+
+   So my solution to that is to try to recognize when we can relax the
+   planemask back to ~0, 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 it when copying from another window (since its alpha channel must
+   also be opaque).
+
+   Note that even when we can't set planemask to all ones, fbBlt may
+   still choose altivec'd code if it's GXcopy and a forwards copy. This
+   is mainly intended for copying from pixmaps to windows. The copy
+   operation used sets alpha to opaque.
+
+   The three macros below are used to implement this, drawing ops look
+   something like this:
+
+   OP {
+       GC_SAVE (gc);
+       GCFUNC_UNWRAP (gc);
+
+       ...
+
+       if (can_accel_xxx (..) && otherwise-suitable)
+          GC_UNSET_PM (gc, dst);
+
+       gc->funcs->OP (gc, ...);
