-   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);

-

-       gc->funcs->OP(gc, ...);

-

-       GC_RESTORE(gc, dst);

-       GCOP_WRAP(gc);

+   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:
