porting shaders to OpenGL 3.2 (first working version! yay )

[mgood7123]

i am trying to port glyphy to OpenGL 3 (OpenGL 3.2 context) with #version 330 core and #version 320 es and i currently get no text rendered

it seems like the default GL context glew creates is 2.1 INTEL-14.7.8 (2.1) tho this might vary

these are my current changes https://github.com/mgood7123/glyphy-opengl3/commit/0104d65f225afa993ef0af3ea3ff135661fe3dc0

I'm open to that but have no experience to offer. Thanks!

i got GL 3 to work, it now renders everything that OpenGL 2 could :)

tho i had to rewrite part of the OPENGL block in demo-common.h to include GL3 headers, only tested on APPLE so not sure if headers will work on linux/windows/android yet

Thanks! Let me test this on my Linux.

Your GL_CHECK_ERROR changes are too noisy. Please use a macro like my existing gl to just prefix all sites that need checking so they look like:

  GL_CHECK glUseProgram (...);
