* SDK-G04000 Rev. 0.01), ATI Technologies: June 1999.
*
* Notes on unimplemented XAA optimizations:
*
* SetClipping: The Rage128 doesn't support the full 16bit registers needed
* for XAA clip rect support.
* SolidFillTrap: This will probably work if we can compute the correct
* Bresenham error values.
* TwoPointLine: The Rage 128 supports Bresenham lines instead.
* DashedLine with non-power-of-two pattern length: Apparently, there is
* no way to set the length of the pattern -- it is always
* assumed to be 8 or 32 (or 1024?).
* ScreenToScreenColorExpandFill: See p. 4-17 of the Technical Reference
* Manual where it states that monochrome expansion of frame
* buffer data is not supported.
* CPUToScreenColorExpandFill, direct: The implementation here uses a hybrid
* direct/indirect method. If we had more data registers,
* then we could do better. If XAA supported a trigger write
* address, the code would be simpler.
* (Alan Hourihane) Update. We now use purely indirect and clip the full
* rectangle. Seems as the direct method has some problems
* with this, although this indirect method is much faster
* than the old method of setting up the engine per scanline.
* This code was the basis of the Radeon work we did.
* Color8x8PatternFill: Apparently, an 8x8 color brush cannot take an 8x8
* pattern from frame buffer memory.
* ImageWrites: See CPUToScreenColorExpandFill.

We could improve this indirect routine by about 10% if the hardware
could accept DWORD padded scanlines, or if XAA could provide bit-packed
data. We might also be able to move to a direct routine if there were
more HOST_DATA registers.
Implementing the hybrid indirect/direct scheme improved performance in a
few areas:
