gdk:gl-context-forward-compatible (context)

context -- a gdk:gl-context object
setting -- a boolean whether context is forward compatible

Gets or sets whether the GL context should be forward compatible.

Forward compatible GL contexts must not support OpenGL functionality that has been marked as deprecated in the requested version. Non-forward compatible GL contexts, on the other hand, must support both deprecated and non deprecated functionality.

The gdk:gl-context object must not be realized or made current prior to calling this function.
