r3xx-r5xx: fix texturing with small macrotiled pixmaps
Pixmaps smaller than a macrotile cannot be used as textures because hardware
automatically switches to macro-linear and therefore sampled pixels are
messed up. This behavior is known as MACRO_SWITCH.
The only sane workaround seems to be not using macrotiling for small pixmaps.
The function RADEONMacroSwitch has been ported from r300g and implements
MACRO_SWITCH the same way it's implemented in hardware. It's been well tested
in r300g.
This commit also fixes blit-based framebuffer reads, which are used for tiled
surfaces in r300g, when ColorTiling is enabled.
