Use the actual PVR2 dithering kernel (standard 4x4 Bayer matrix) used on
real hardware.
Fixes the screen melt effect of Doom64 (per-pixel only).
Issue #1939
Using src=OTHER_COLOR with destination secondary accumulator should use
the secondary accumulator color, not the final one.
Fixes dark gun in Doom 64 with Ultra graphics (bump mapping).
Issue #1771
Disable blending when rendering a-buffers. Fixes ECW Anarchy Rulz black
title screen and Demolition Racer glitchy end of race screen.
Use palette in the depth pass for punch-through polygons using palette
texture. Fixes shadow issue in Alone in the Dark.
Copy ouput fbo to geom_fbo before drawing. Fixes missing transparent
polygons in subsequent partial renders. Fixes Test Drive Le Mans missing
labels in loading screen.
Issue #1262
gl, vk, dx11, dx9: implement ordered dithering in GLSL/HLSL
refactor framebuffer and texture writes to vram
don't expand color data when reading planar textures
Shift the framebuffer according to VO_STARTX and VO_STARTY.
Issue #594
GlVertexArray class to handle vertex arrays (or lack thereof)
lr: Fix PowerVR2 filter including in full fb emu mode. Use quad to draw
vmus and lightgun xhairs.
* cmake: use c++17
* Use std::size
* Use std::make_unique
* Use std::clamp
* Use structured binding
* Use [[fallthrough]]
* Use enable_if_t/is_enum_v/is_integral_v/is_same_v
* Use if constexpr
* Use try_emplace
* Use auto for iterators
* Use inline variables
Region tile object list pointers can be identical for op and tr modvols,
in which case tr modvols should be drawn using op modvols geometry.
Used by crazy taxi 1/2, alien front online, daytona usa and probably
many others.
Issue #717
shared libraries containing gnuc unique symbols are never unloaded on
linux, and possibly other platforms. So don't terminate the emulator on
deinit and init it only once.
Issue #566
gl4: buffer not released on term() was causing crashes or black screen when restarted.
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.
Use w=1 to avoid multiply/divide of xy as in dx9
Disable rendering when video output disabled
Use original w value in pixel struct to avoid precision loss (samsptk)
vk oit: missing memory barrier was producing Tr modvol glitches (JSR)
gl oit: Tr modvol needs full vertex shader
Support VO_STARTX and VO_STARTY for shifting displayed frame
Add glm to deps
Calculate NDC, scissoring and viewport matrices once
Reduce code duplication
Depth testing is done in the fragment shader so it shouldn't be done
in the a-buffer shader for the first pixel, or until the depth is updated.
Fixes flashlight and lightstorm effects in Alone in the Dark
90deg CC screen rotation option for some arcade games
Fix scissoring and clipping when screen scaling/stretching/rotating
Clear shader cache when screen rotation changes
Properly delete all gl programs and shaders when needed
implement screen scaling for per-pixel renderer
fix output FBO not being freed/recreated when GL context is reset
refactor DrawQuad on per-pixel renderer
