Then why are there separate enables for this and NV_image_formats in the gl_extensions object? Note that doing this properly here is a bit tricky -- it's not like one would do "#extension GL_EXT_texture_norm16: enable". So you'd have to check in the GL context for whether it's enabled somehow. [As an aside, any impl that supports ARB_shader_image_load_store will support all of this. I don't know what the practical restrictions are on ES hardware -- Adreno does norm16 just fine, but others might not?] -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
