class exec_info():
"""Information relating GL APIs to a function.
Each of the four attributes of this class, compatibility, core, es1, and
es2, specify the minimum API version where a function can possibly exist
in Mesa. The version is specified as an integer of (real GL version *
10). For example, glCreateProgram was added in OpenGL 2.0, so
compatibility=20 and core=31.
If the attribute is None, then it cannot be supported by that
API. For example, glNewList was removed from core profiles, so
compatibility=10 and core=None.
Each of the attributes that is not None must have a valid value. The
valid ranges are:
compatiblity: [10, 30]
core: [31, )
es1: [10, 11]
es2: [20, )
These ranges are enforced by the constructor.
