[mapserver-dev] OpenGL check in

[Toby Rahilly]

I have checked in the Opengl update to the mapserver6 sandbox.

Still TO DO:
* Optimized by using textures for symbols and not creating an OpenGL
context for every new image.
* I was not able to get line symbols to work in any renderer, have
they changed for Mapserver 6?

I have tested on Windows 7 and Ubuntu 8 both with Nvidia drivers.

Any testing on other platforms/video cards would be greatly
appreciated, thanks Tamas! You will need to compile with the FTGL
library which is used for text rendering. The driver is "OGL".

You can compare some renderings here:
