1f0c69a0e9 - some cleanup after GL 2.x code removal
- reinstated burn warp with shader based code.

2925c96b59 removed all GL 2.x code.
After thinking about it for a day or so I believe it's the best option to remove all compatibility code because it's a major obstacle for a transition to a core profile.

d5dceb6874 - changed alpha texture handling to avoid using the deprecated GL_ALPHA8 texture format unless we have a compatibility context of an older GL version. 2014-06-21 12:52:19 +02:00

a26fbc74f0 Fix compilation errors in latest texture-related changes
GCC and Clang complain about non-POD type passed to variadic function.

4d005bdfa0 shader rework
All those special shaders have been merged together.
Mostly working but the non-shader lighting seems a bit broken.

b9a6fe80a4 Do not use the shader to handle STYLEF_RedIsAlpha.
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...

This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

978ace241c - removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state.
- removed cm parameter from many functions.

887d35d559 - remove colormap from texture generation parameters. The one remaining special case, alpha texture on old hardware is now handled by the currently set texture mode at the time of use.
- use the cleaned up decal lighting code from the first GLEW branch.

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.
