39e2113c73 OpenGL2: Misc fixes and cleanup 
Fix two constants in GLSL shaders. Remove f suffix from float and fix
int to float assignment. They were causing shader compile errors in
OpenGL ES 2 context.

Remove disabling clip plane. Clip plane is unused and never enabled in
the opengl2 renderer. Remove disabling it to avoid causing a GL error
when using OpenGL 3.2 core profile or OpenGL ES.

Make VAO cache vertex stride be size of srfVert_t since that is what
is uploaded to the GPU. No behavior change. There is a disabled debug
id in srfVert_t though which if enabled changes srfVert_t size.

59b1262b82 Fix floating point precision loss in renderer [part 2] 
Fix floatTime using float precision instead of double using GCC.
Fix R_BindAnimatedImage to be in sync with function table.
Fix vertexDeform bulge, vertexDeform normals, noise wave function
at high level time.

Revert unnecessary float -> double conversions.

30fdd88c9f Fix floating point precision loss in renderer [part 1] 
Patch for https://bugzilla.icculus.org/show_bug.cgi?id=5931 by
Eugene C. from 2013 plus recent fix for tcMod rotate.

I merged the changes into the OpenGL2 renderer though the fix for
tcMod turb doesn't translate.
