- 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 three macros below are used to implement this. Drawing ops that can
- potentially have their planemask relaxed look like:
-
- OP {
- GC_SAVE(gc);
- GCOP_UNWRAP(gc);
-
- ...
-
- if (canAccelxxx(..) && otherwise-suitable)
- GC_UNSET_PM(gc, dst);
