Geoffrey McRae	b4b4a37b2b	[client] egl: switch to using GL_TEXTURE_EXTERNAL_OES for DMABUF ... According to Erik @ NVidia the open source NVidia driver will not create a EGLImage from a DMABUF if the target is not GL_TEXTURE_EXTERNAL_OES. This change set converts the dmabuf texture from GL_TEXTURE_2D to GL_TEXTURE_EXTERNAL_OES and at runtime performs a global search & replace on fragment shaders as needed to remain compatible, replacing `sampler2D` with `samplerExternalOES`.

Geoffrey McRae	91b0cba145	[client] egl: switch from mediump to highp ... This fixes a rounding issue on certain hardware (NVidia) which actually implement mediump as half precision (16-bit) float. It's safe to assume `highp` is available as if the GPU does not support it, then the shader compiler will try to find a lower precision that is supported by the GPU	2023-03-05 14:10:21 +11:00
