[Flightgear-devel] GLU/Canvas

[Erik H. <er...@eh...>]

Hi,

In an effort to limit the number of dependencies I noticed that canvas 
is the only place that uses GLU.

I think one dependency is easy to remove by replacing 
gluOrtho2D(0,width,0,height) by glOrtho(0,width,0,height,0,1) in shContext.c

Another file that uses GLU is shImage.c which calls
gluScaleImage when a texture in not a power of two. But since we control 
the texture sizes ourselves I doubt this code is ever called.

Erik
