Documentation
vendor :: GettableStateVar String
renderer :: GettableStateVar String
glVersion :: GettableStateVar String
glExtensions :: GettableStateVar [String]
shadingLanguageVersion :: GettableStateVar String
majorMinor :: GettableStateVar String -> GettableStateVar (Int, Int)
A utility function to be used with e.g. `glVersion` or `shadingLanguageVersion`, transforming a variable containing a string of the form major.minor[optional rest] into a variable containing a numeric major/minor version. If the string is malformed, which should never happen with a sane OpenGL implementation, it is transformed to `(-1,-1)`.
