major cleanup of the texture manager: - use sampler objects to avoid creating up to 4 different system textures for one game texture just because of different clamping settings. - avoids flushing all textures for change of texture filter mode. - separate sprite and regular dimensions on the material level to have better control over which one gets used. It's now an explicit parameter of ValidateTexture. The main reason for this change is better handling of wall sprites which may not be subjected to such handling. - create mipmaps based on use case, not texture type. - allows removal of FCloneTexture hack for proper sharing of the same sprite for decals and other purposes. - better precaching of skyboxes. 2014-08-22 21:50:38 +00:00			`#ifndef __GL_SAMPLERS_H`

fixed: The sampler object for camera textures was never initialized. 2014-09-17 08:52:34 +00:00			`unsigned int mSamplers[7];`

- allow the engine to run without sampler objects. This will create some overhead in the texture code, but that's still better than having to error out on those few systems where it may be an issue. 2016-04-22 17:54:51 +00:00			`BYTE Bind(int texunit, int num, int lastval);`
