+//NOTE: You can find the set of original Unai poly routines (disabled now)
+// at the bottom end of this file.
+
+//senquack - Original Unai GPU poly routines have been replaced with new
+// ones based on DrHell routines. The original routines suffered from
+// shifted rows, causing many quads to have their first triangle drawn
+// correctly, but the second triangle would randomly have pixels shifted
+// either left or right or entire rows not drawn at all. Furthermore,
+// some times entire triangles seemed to be either missing or only
+// partially drawn (most clearly seen in sky/road textures in NFS3,
+// clock tower in beginning of Castlevania SOTN). Pixel gaps were
+// prevalent.
+//
+// Since DrHell GPU didn't seem to exhibit these artifacts at all, I adapted
+// its routines to GPU Unai (Unai was probably already originally based on it).
+// DrHell uses 22.10 fixed point instead of Unai's 16.16, so gpu_fixedpoint.h
+// required modification as well as gpu_inner.h (where gpuPolySpanFn driver
+// functions are).
+//
+// Originally, I tried to patch up original Unai routines and got as far
+// as fixing the shifted rows, but still had other problem of triangles rendered
+// wrong (black triangular gaps in NFS3 sky, clock tower in Castlevania SOTN).
+// I eventually gave up. Even after rewriting/adapting the routines,
+// however, I still had some random pixel droupouts, specifically in
+// NFS3 sky texture. I discovered that gpu_inner.h gpuPolySpanFn function
+// was taking optimizations to an extreme and packing u/v texture coords
+// into one 32-bit word, reducing their accuracy. Only once they were
+// handled in full-accuracy individual words was that problem fixed.
+//
+// NOTE: I also added support for doing divisions using the FPU, either
+// with normal division or multiplication-by-reciprocal.
+// To use float division, GPU_UNAI_USE_FLOATMATH should be defined.
+// To use float mult-by-reciprocal, GPU_UNAI_USE_FLOAT_DIV_MULTINV
+// can be specified (GPU_UNAI_USE_FLOATMATH must also be specified)
+// To use inaccurate fixed-point mult-by-reciprocal, define
+// GPU_UNAI_USE_INT_DIV_MULTINV. This is the default on older
+// ARM devices like Wiz/Caanoo that have neither integer division
+// in hardware or an FPU. It results in some pixel dropouts,
+// texture glitches, but less than the original GPU UNAI code.
+//
+// If nothing is specified, integer division will be used.
+//
+// NOTE 2: Even with MIPS32R2 having FPU recip.s instruction, and it is
+// used when this platform is detected, I found it not to give any
+// noticeable speedup over normal float division (in fact seemed a tiny
+// tiny bit slower). I also found float division to not provide any
+// noticeable speedups versus integer division on MISP32R2 platform.
+// Granted, the differences were all around .5 FPS or less.
+//
+// TODO:
+// * See if anything can be done about remaining pixel gaps in Gran
+// Turismo car models, track.
+// * Find better way of passing parameters to gpuPolySpanFn functions than
+// through original Unai method of using global variables u4,v4,du4 etc.
+// * Come up with some newer way of drawing rows of pixels than by calling
+// gpuPolySpanFn through function pointer. For every row, at least on
+// MIPS platforms, many registers are having to be pushed/popped from stack
+// on each call, which is strange since MIPS has so many registers.
+// * MIPS MXU/ASM optimized gpuPolySpanFn ?

+// slopes between 0.5 and 2.0 (diagonal runs of pixels) to be handled
+// identically to the traditional horizontal/vertical run-slice method.
