I've started using WebGL and am pleased with how easy it is to leverage my OpenGL (and by extension OpenGL ES) experience. However, my understanding is as follows:

OpenGL ES is a subset of OpenGL
WebGL is a subset of OpenGL ES

Is this correct for both cases? If so, are there resources for detailing which features are missing?

For example, one notable missing feature is glPushMatrix and glPopMatrix. I don't see those in WebGL, but in my searches I cannot find them referenced in OpenGL ES material either.

I have a simple iPhone application which uses OpenGL ES (v1) to draw a line based on the touches of the user. In the XCode Simulator, the code works perfectly. However, when I install the app onto an iPod or iPhone, the OpenGL ES view "flashes" when drawing the line. If I disable the line drawing… >>> More
