Zack Middleton 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.

Zack Middleton 14cc4cc6cb OpenGL2: Fix world VAO cache drawing when glIndex_t is unsigned short 
OpenGL ES is only required to support unsigned short for element buffer
values.

R_DrawElements() firstIndex argument was glIndex_t which caused element
indexes to wrap around to 0 when glIndex_t is an unsigned short.
(glIndex_t is an index into the vertexes buffer, not element buffer.)
Change it to 'int' like tess.firstIndex which is passed to
R_DrawElements().

World VAO cache buffer size allowed storing more vertexes than unsigned
short glIndex_t could reference. This resulted in the vertex indexes in
the element buffer wrapping around to 0.

Zack Middleton e8450cae33 OpenGL2: Use ri.Error instead of Com_Error in tr_vbo.c 
Com_Error is a wrapper for ri.Error. Use it directly.
