be more consistent with debug options

fix tpyo
thanks rin@

make debug output a bit more manageable

consistently use SX_RENDER_DEBUG, hide some more debug goop

make ALU instructions use the same format as load/store instructions
same binary generated

add macros to simplify issuing SX instructions, hide the address alignment /
displacement shenanigans SX needs, and make the code more resemble the
inline assembler source it arguably is

avoid stalling the CPU by letting the SX instruction FIFO drain every couple
of memory instructions.
No more missed IPIs when building stuff in an xterm so far...

do up to 4 pixels at a time CG14Comp_Over*()

RGB/BGR-flip source images in CG14Comp_Over32*() with non-solid sources
as well. This takes care of most remaining RGB/BGR issues in xrender.
Next step: do more than one pixel at a time in those operations.

support PictOpAdd with A8 source and ARGB/ABGR destination
now labels in windowmaker look right again

do PictOpOver operations 4 pixels at a time - this is a vector processor,
let's do some vector processing
-> about 40% speed increase

adapt to xorg 1.18

now we get PictOpOver with no source alpha and a 32bit mask right
( mostly gtk2 icons and button images )
TODO: RGB vs. BGR

support PictOpOver with 32bit source and mask

"support" PictOpOver with 32bit source and 32bit mask
this needs more work but at least it makes things like gkrellm readable

- fetch fill colour for text drawing in CheckComposite, swap red and blue
channels as needed
- support solid sources without a drawable
now gtk2 apps no longer crash the Xserver and text is drawn in the correct
colour
next step: 32bit PictOpOver with 32bit mask, gtk2 seems to use those a lot

support PictOpOver with 32bit source without alpha, alpha in mask
now KDE3 looks mostly right
( yes, it's almost usable on a 125MHz HyperSPARC )
gtk2 apps still crash though

missed one
( move CG14Comp_Over32Solid() too )

- support PictOpSrc, mask is ignored so far
- support PictOpOver with non-solid source, with or without mask - now QT3
icons are rendered properly
- move render operations into their own file
