Re : 2.0b7 Skybox - not working

Figured it out... wish this was somehow automatically included in Processing.  Have to load the matrix (not sure if it is in each draw or just once in the setup).  As described by Andres:

You have to do the glLoadMatrixf() call manually because the OpenGL renderer only uses functions available in the GLES2 API, and all the matrix-related functions are gone in GLES2 (and GL 3.2+).
