add undefd codepath for correct use of the 18bit DAC path (which seems to be triggered for all games)
...
the volume correction to bring the data back into a valid range is not really needed in practice though, only Daytona2 seems to need it, and also only extremely rarely, so lets just live with a tiny bit of clamping for that game then
while add it, make some formatting similar to MAME, and add one comment regarding a most likely wrong recent MAME change

Incomplete texture headers uploaded via FIFO are now discarded. Ski Champ sends one more 32-bit word via DMA than it should which was causing Supermodel to erroneously intepret the extra word as another texture

Rewrite the whole project for GL4+. I figured if we removed the limitation of a legacy rendering API we could improve things a bit. With GL4+ we can do unsigned integer math in the shaders. This allows us to upload a direct copy of the real3d texture sheet, and texture directly from this memory given the x/y pos and type. This massively simplifies the binding and invalidation code. Also the crazy corner cases will work because it essentially works the same way as the original hardware.
...
The standard triangle render requires gl 4.1 core, so should work on mac. The quad renderer runs on 4.5 core. The legacy renderer should still work, and when enabled a regular opengl context will be created, which allows functions marked depreciated in the core profiles to still work. This will only work in windows/linux I think. Apple doesn't support this.
A GL 4.1 GPU is now the min required spec. Sorry if you have an OLDER gpu. GL 4.1 is over 12 years old now.
This is a big update so I apologise in advance if I accidently broke something :]

Upgrade the glsl shader class a bit. Add a const char* comparitor so we can use a map with a simple "string" key. Fine to use when performance is not critical.

Optimize quad rendering by replacing the double computations for the area computation with the equivalent shoelace algorithm along with kahans algorithm to compute the cross products. In addition pull out the /w to the end, which increases precision even more.
...
Thus making the result similar to the fp64 version, tested e.g. with harleys first person mode (all artifacts still gone as before).
Improves perf on low end boards (e.g. Intel) dramatically (10fps with harley before, now 70 on my laptop), and even on higher end (e.g. NVIDIA laptop, quads are now faster than tri pipeline on my laptop).
