glsl: Parse the allowed image format qualifiers in GLSL ES 3.1.
This includes the minimum required desktop/ES GLSL version in the format qualifier table in anticipation of new GLSL versions extending the set of supported image formats. According to section 4.4.7 of the GLSL ES 3.1 spec: "The format layout qualifier identifiers for image variable declarations are: [...] rgba32f rgba16f r32f rgba8 rgba8_snorm [...] rgba32i rgba16i rgba8i r32i [...] rgba32ui rgba16ui rgba8ui r32ui" Reviewed-by: Tapani Pälli <[email protected]>
