0f3f2e361f GLES: More uint const paranoia. 
We don't use indexing on GLES now, but better to stay consistent.

3b46409350 Vertex shaders: On platforms with uniform buffers, use indexing and loop for real over the lights. 
Strangely, greatly speeds up pipeline creation on PowerVR.

3d376b0ab7 Remove the rather redundant DoTexture flag from vshaders. 
Slightly reduces the number of unique vertex shaders but doesn't do much
for the pipeline count, as the fragment shader has a tex flag. Still
worth doing for the simplification.

f49f7c6371 D3D9: Force branch usage for fog compute. 
When using `[flatten]`/default, it picks the wrong value, seemingly always
taking the else case (even if the condition is changed or reversed.)

f3acdb9da8 GLES: Avoid a shader constant error. 
Some Adreno drivers interpret 0u as an integer.

86d748fa0c GLES: Use uint for uint shift amounts. 
This seems to cause trouble for some Adreno drivers as well.

eae85836c9 GPU: Add a small error-compensation to depth clip. 
This was causing a depth that should've calculated as zero to be clipped,
because the multiply and division resulted in a value that was off by
about 2 / pow(2, 24) in the negative direction.

c6084c16c3 Fix GLSL compilation issues on really old Adreno drivers. 
They don't seem to accept unsigned integers as switch cases.

Fixes some stuff in #16295 , not sure if all of it.

0f37854ef9 Drop some D3D11 screen rotation support (was only used on Windows Phone) 2022-11-05 22:17:06 +01:00

ad6725b684 VK/D3D11: Move the rarely used "u_rotation" uniform to the frame uniform buffer. 
This uniform is used in two cases:

* Non-buffered rendering in Vulkan, software transform
* Non-buffered rendering in D3D11 level 9 on Windows Phone, software transform
  - which I don't think anyone builds for anymore

Nice to not have it in the main uniform buffer, but mainly a
demonstrator/test of moving stuff to the new frame-global buffer, and
setting up the infrastructure.

bc3d3cf9fb GPU: Optimize clip distances needed. 
We only need to write one clip distance to clip clamped depth, since we
don't clamp when it needs clipping on both sides.

8025def8d2 Vulkan: Clip to neg z in the geometry shader. 
This is only used when clip distance is unsupported, such as on Mali.
