09f4071436 Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code. 2014-05-11 13:27:51 +02:00

94b06900cb - got rid of a lot of stuff that's no longer required with GLEW. 
- replaced GLUs texture scaling with our own function. This is only used to scale down textures larger than what the hardware can handle so we do not need a dependency to an essentially deprecated library for it.

69af73d9b9 - alternative configuration using GLEW to get extension functions. This requires GL 2.0, though so it won't be promoted to the mainline for the time being. 
- removed all pre GL 2.0 support.

a72b94e80c - fixed: Warped textures were recreated each time they were bound. 
- fixed: Models were never freed.

0ff21c3af7 - fixed: Sprites may never be used as a base of a texture redirect 
Due to autoexpansion to remove filtering artifacts their dimensions are not the same as for patches. But if the sprite hadn't been used yet this information won't have been set yet.

b61ef3a107 - bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2. 
- removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore.
- disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.
