Where exactly can I get the header and library files for OpenGL 1.2 or higher?
I am currently using v1.1 however I need to use glDrawPixels() to display buffer source data in the format RGB 5-6-5.
The GL_UNSIGNED_SHORT_5_6_5 type is unsupported in v1.1 therefore I need v1.2 or above.
At present I am separately copying the red, green and blue components via masking from the source buffer into a new buffer then using the GL_UNSIGNED_BYTE type however the overhead of this conversion is causing an unacceptable drop in frame rate
I have search extensively for v1.2 on the net however I am getting nowhere, any help would be greatly appreciated
