mesa: Set initial internal format of a texture to GL_RGBA
From OpenGL 4.0 spec, page 398: "The initial internal format of a texel array is RGBA instead of 1. TEXTURE_COMPONENTS is deprecated; always use TEXTURE_INTERNAL_FORMAT." Fixes Khronos OpenGL CTS test failure: proxy_textures_invalid_size Cc: <[email protected]> Signed-off-by: Anuj Phogat <[email protected]> Reviewed-by: Brian Paul <[email protected]>
