[Bf-committers] OpenGL fast option (interpolation benchmark)

[Ton Roosendaal]

Hi,

An OpenGL "Profile" can be a set of user settings to tweak use of  
OpenGL based on the specific features your 3d card supports, or  
features you prefer support for.
It is a recommended method for moving on to higher OpenGL version  
features (like shaders) but can also be used for tweaking missing  
functionality in drivers or 3d cards.

It does mean that we'll have to wrap code internally for all suspicious  
commands. This was already done for Linux (DRI has no glPointSize) and  
for Mac (intel gfx has different glFlush() behaviour). It's also time  
to define which of the opengl 1.1 feature set we'll stick to, and what  
will be taboo (3d cards tend to only support limited features  
accellerated anyway).

On the positive side, this can enable developers to make a GPU based  
compositing library for example. :)
