 /*
- * GL support.
- *
- * Emscripten supports the WebGL-friendly subset of OpenGL, basically what
- * maps directly to WebGL. This includes almost all of OpenGL ES 2.0,
- * except for client-side arrays. The reason they are missing from WebGL
- * is because they are less efficient than properly using GPU-side data.
- * Similarly, if we emulated client-side arrays here, we would end up
- * with very bad performance, since we would need to upload the data
- * on each call to glDrawArrays etc. (Even if there are two calls one
- * after the other, we can't know the data did not change!) So in
- * practical terms full OpenGL ES 2.0 emulation would be convenient,
- * but lead to bad performance so in practice you would need to properly
- * rewrite your code to a WebGL-friendly subset anyhow.
- *
- * Thankfully, rewriting to that subset is general fairly easy. See
- * the files in tests/glbook for some simple examples ported to that
- * subset.
- *
- * Regarding OpenGL aspects present on desktop GL or on OpenGL ES prior
- * to 2.0, we also do not support immediate mode (glBegin/glEnd), GL_QUADS,
- * etc. Some of these might make sense to emulate, some might not.
+ * GL support. See https://github.com/kripken/emscripten/wiki/OpenGL-support
+ * for current status.
