CalculateDepthDraw guarded depthVertexCount_ with vertexCount, which is the
index count - but depthVertexCount_ grows by the number of decoded vertices,
which for an indexed draw can be far larger. Two draws with 6 indices spanning
40000 vertices each therefore passed the check and wrote ~700KB past the end of
depthTransformed_. It also never bounded depthIndexCount_ against depthIndices_
at all, which only has room for 3 indices per vertex slot while draws routinely
produce more. Pass the decoded count in separately and check both.
DepthRasterClipIndexedTriangles duplicated culling-disabled triangles twice: once
in the collect loop (added for Syphon Filter, #21498) and again in the output
stage, which was the older code and should have been removed then. So it emitted
four triangles per input triangle into buffers sized for one, and did twice the
rasterization work it needed to in that mode. Removed the output-stage copy, and
gave the function the output capacity so it stops when full - even at 2x, a
culling-disabled draw over ~32k indices doesn't fit.

Previously, "Smart 2D texture filtering" was limited to through-mode
draws, but many games use fully transformed draws to do 2D elements.
An example of this is Outrun in the menus, and it's always been plagued by
horrible filtering artifacts.
With the improved Smart 2D texture filtering, the artifacts are gone!
Of course, instead of glitchy bilinear you instead get point sampled
texturing so it looks more pixellated, but no more ugly borders between letters
in the game.
Some games render HLE sceFont glyphs into small VRAM-backed framebuffers and immediately sample them as textures. This needs both the source glyph buffer and the temporary render target to be preserved before later commands overwrite or rebind them.
Save first-frame data from the previous render target before creating a new framebuffer, since ResizeFramebufFBO() makes the new framebuffer current. Also flush pending draws before PGF writes over a glyph buffer that may still be referenced by queued texture draws.
Backend software transform normally reports safe framebuffer size during draw flush, but first-frame readback can happen before queued draws reach that path. Estimate through-mode rectangle/triangle bounds before SubmitPrim() and feed those bounds to SetSafeSize(), using actual vertices clamped to scissor instead of a tiny-target heuristic.
