OpenGL extension ARB.shader_precision
This module customises the behaviour of the OpenGL.raw.GL.ARB.shader_precision to provide a more Python-friendly API
Overview (from the spec)
This extension more clearly restricts the precision requirements of implementations of the GLSL specification. These include precision of arithmetic operations (operators '+', '/', ...), transcendentals (log, exp, pow, reciprocal sqrt, ...), when NaNs (not a number) and INFs (infinities) will be supported and generated, and denorm flushing behavior. Trigonometric built-ins and some other categories of built-ins are not addressed.
