class _ErrorChecker(
object
):
Global error-checking object
This error checker also includes "safeGetError" functionality,
that is, it allows for checking for context validity as well
as for glBegin/glEnd checking.

glCheckError
Base GL Error checker compatible with new ctypes errcheck protocol
This function will raise a GLError with just the calling information
available at the C-calling level, i.e. the error code, cArguments,
baseOperation and result. Higher-level code is responsible for any
extra annotations.
Note:
glCheckError relies on glBegin/glEnd interactions to
prevent glGetError being called during a glBegin/glEnd
sequence. If you are calling glBegin/glEnd in C you
should call onBegin and onEnd appropriately.
onBegin
Called by glBegin to record the fact that glGetError won't work
onEnd
Called by glEnd to record the fact that glGetError will work
