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.
