OpenGL errors are present in nux

The following occurs when running unity from trunk:

WARN 2012-11-29 12:04:27 nux.gl RenderingPipeGLSL.cpp:2997 [CheckGLError] OpenGL Error 1282 (invalid operation)

As well as:

Following the docs from open gl:

Only a subset of GL commands can be used between glBegin and glEnd. The commands are glVertex, glColor, glIndex, glNormal, glTexCoord, glEvalCoord, glEvalPoint, glArrayElement, glMaterial, and glEdgeFlag. Also, it is acceptable to use glCallList or glCallLists to execute display lists that include only the preceding commands. If any other GL command is executed between glBegin and glEnd, the error flag is set and the command is ignored.

and the wraning occurs:

GL_INVALID_OPERATION is generated if a command other than glVertex, glColor, glIndex, glNormal, glTexCoord, glEvalCoord, glEvalPoint, glArrayElement, glMaterial, glEdgeFlag, glCallList, or glCallLists is executed between the execution of glBegin and the corresponding execution glEnd.

This means that there is something not correctly used within nux regarding the open gl api.
