dx11: naomi2 support
n2: ambient color was swapping red and blue
gl, dx11: don't write depth in per-strip to avoid missing geometry,
prefer wrong depth order/blending for now
optimize naomi2 per-triangle sorting
elan: Get rid of geometry shader and do geometry clipping manually.
pvr: Aggressively merge transparent polys in per-triangl and OIT mode, duplicating the last vertex to merge opposite cull mode strips.
gl4: reset OIT pointers in final shader. No need for clear pass.
gl4: alternate between 2 buffers for verts.index/tr poly params.
gl4: use gl_VertexID + poly number for poly index.
gl: new GlBuffer class.
emulate elan v10 (fixes modvol in vf4, initd, beachspiker, wldrider)
wrong color order for model and vtx color
model param override xor support
improved light direction precision. Angle attenuation algo change
get rid of alpha light and modifier volume hacks
texture dma xfer from main and elan ram
gl4: use geometry only vtx and geom shaders for depth pass
2-volume support
pvr: link multipass TA contexts. Each pass has its own.
pvr: get rid of context pool
naomi2: constant color shading. Use model diffuse and specular
selection. Don't use vtx color for offset color.
naomi2: pseudo-parallel lights fix
naomi2: pass-through TA data needs forced list type. Terminate with
end-of-list
enable RTT copy to vram for Beach Spikers
