  As well as:

  WARN  2012-11-29 09:06:53 nux.gl IOpenGLTexture2D.cpp:83 [CheckGLError] OpenGL Error 1282 (invalid operation)

  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.
