60bd25582c Vulkan: Remove wide line handling. 
No longer used, since we convert lines to triangles now.

33598f2e75 GPU: Support clip and cull distances separately. 
Older GL devices, and it seems Apple devices, may not support cull.

7b00c4a572 GPU: Move Z/W equal hack to bugs from supports. 
It's really a bug (might even ideally cap the version?), and we already
have other bugs handled the same way.

32c9728c0c Some cleanups in GL feature and shader language detection. 
Gets rid of many wrong or bad checks for IsCoreContext.

f3ebd6553d Turn off vertex range culling in bezier/spline calls. 
When we do lower res tess than the real PSP, we cant trust the game to not cause range culling to kick in.

Fixes #11692

575ae376a9 Don't try to texture from depth if not supported by backend. Works around #13621 2020-11-10 23:36:33 +01:00

3d289594f9 ShaderBlend and FramebufferRead are separate concepts. Reflect that in naming. 
The former has forms that don't need to read the framebuffer.

This exposes that some logic is wrong...

dc0f7ca8ee VK: Copy depth buffer if we can't blit. Some GPUs can't blit to depth. 
Fixes some recent issues with Intel GPUs on Vulkan.

d0f7b1e30f Make the implementations of CopyFramebufferDepth more similar. 
Also avoid matching framebuffers with bad z for copies.

eadd3c5785 Remove the LARGE_VIEWPORTS separate path. The fewer paths the better, all need to work anyway. 
Required fixing a bug in ShaderUniforms.cpp (used by D3D11 and Vulkan,
the two backends that previously exposed LARGE_VIEWPORTS).

0462c01228 Workaround ARM Mali depth hardware bug. Fixes #11937 
When triangles coincide with the Z=1 plane in specific ways, triggered
by Burnout Legends' sky for example, the depth buffer gets corrupted.

This is worked around here by slightly rescaling Z. This type of
workaround is recommended by ARM driver engineers.

Ugly but what can you do when the hardware is bugged. I've done quick
tests on a number of games with no issues.

77f0499f7f GPU: Rename clipping flag to depth clamp. 
It seems to just to depth clamp.  When depth clamp happens, it affects
clipping a little, but only for vertices that needed clamping.

d4ff7cc928 Spline: Simplify uniforms/dirty to one check.

splines.
