This new plugin is based on Unai but is more accurate and fixes a few issues.
According to some tests on real hardware :
fps old new
spyro1 130 112
tekken3 95 68
nfs3 107 91
Because of this, it was decided to make it separate from the "Old" Unai.
Note that this doesn't have the threading changes from libretro's fork yet :
this will be for another PR.

+//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 ?

+// GPU internal line drawing functions

+// Rewritten October 2016 by senquack:
+// Instead of one pixel at a time, lines are now drawn in runs of pixels,
+// whether vertical, horizontal, or diagonal. A new inner driver
+// 'gpuPixelSpanFn' is used, as well as an enhanced Bresenham run-slice
+// algorithm. For more information, see the following:
+//
+// Michael Abrash - Graphics Programming Black Book
+// Chapters 35 - 36 (does not implement diagonal runs)
+// http://www.drdobbs.com/parallel/graphics-programming-black-book/184404919
+// http://www.jagregory.com/abrash-black-book/
+//
+// Article by Andrew Delong (does not implement diagonal runs)
+// http://timetraces.ca/nw/drawline.htm
+//
+// 'Run-Based Multi-Point Line Drawing' by Eun Jae Lee & Larry F. Hodges
+// https://smartech.gatech.edu/bitstream/handle/1853/3632/93-22.pdf
+// Provided the idea of doing a half-octant transform allowing lines with
+// slopes between 0.5 and 2.0 (diagonal runs of pixels) to be handled
+// identically to the traditional horizontal/vertical run-slice method.
+
+// Use 16.16 fixed point precision for line math.
+// NOTE: Gouraud colors used by gpuPixelSpanFn can use a different precision.
+#define GPU_LINE_FIXED_BITS 16
+
+// If defined, Gouraud lines will use fixed-point multiply-by-inverse to
