- There are two issues we must contend with when drawing. These are
- controlled with ROOTLESS_PROTECT_ALPHA and RootlessAccelInit().
-
- 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 RootlessAccelInit() is called.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:
-
- OP {
- GC_SAVE(gc);
- GCOP_UNWRAP(gc);
-
- ...
-
- if (canAccelxxx(..) && otherwise-suitable)
- GC_UNSET_PM(gc, dst);

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

+ There are two issues we must contend with when drawing. These are
+ controlled with ROOTLESS_PROTECT_ALPHA and RootlessAccelInit().
+
+ 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 RootlessAccelInit() is called.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:
