Implement all operators specified for GLSL #if expressions (with tests). The operator coverage here is quite complete. The one big thing missing is that we are not yet doing macro expansion in #if lines. This makes the whole support fairly useless, so we plan to fix that shortcoming right away. 2010-05-24 10:37:38 -07:00			`#if defined foo`
