Added RGBA5551 compatibility in the rasterizer
This allows Virtual Console games to display properly.

c564c21668
GPU: Implemented bits 3 and 1 from the display transfer flags.
Bit 3 is used to specify a raw copy, where no processing is done to the data, seems to behave exactly as a DMA.
Bit 1 is used to specify whether to convert from a tiled format to a linear format or viceversa.

Pica/TextureEnvironment: Treat texture combiner source 1 as the PrimaryColor.
Not really sure where the difference is, but some applications seem to use this 1:1 the same way...

365236fa4c
Pica: Cleanup clipping code and change screenspace z to range from -1..0.
The change in depth range seems to reflect better to what applications are expecting, and makes for cleaner code overall (hence is more likely to reflect hardware behavior).

Fix Min and Max blend equations

ef24e72b26
Asserts: break/crash program, fit to style guide; log.h->assert.h
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)
Also removed some GEKKO cruft.
