We are declaring we require ARB_shader_image_load_store in the shader, this isn't an extension on GLES because it is part of the GLSL ES 3.1 spec.
If we are running as GLES then just not put it in the shaders.
This drops the "feature" to load level 0 from the custom texture
and all other levels from the native one if the size matches.
But in my opinion, when a custom texture only provide one level,
no more should be used at all.
GLES3 spec is worthless and only returns a boolean result for occlusion queries. This is fine for simple cellular games but we need more than a
boolean result.
Thankfully Nvidia exposes GL_NV_occlusion_queries under a OpenGL ES extension, which allows us to get full samples rendered.
The only device this change affects is the Nexus 9, since it is an Nvidia K1 crippled to only support OpenGL ES.
No other OpenGL ES device that I know of supports this extension.
A number of games make an EFB copy in I4/I8 format, then use it as a
texture in C4/C8 format. Detect when this happens, and decode the copy on
the GPU using the specified palette.
This has a few advantages: it allows using EFB2Tex for a few more games,
it, it preserves the resolution of scaled EFB copies, and it's probably a
bit faster.
D3D only at the moment, but porting to OpenGL should be straightforward..
