- Textured automap would crash due to an additional parameter in the software renderer to the FillSimplePoly function call, causing stack issues.

- changed order of SwapBuffers and glFinish call. The new order with glFinish coming last is recommended by OpenGL and it fixes a stalling problem with portals and camera textures visible at the same time.
...
- check and use WGL_EXT_swap_control_tear extension. The above change makes the system always wait for a full vsync with a wglSwapInterval of 1, so it now uses the official extension that enables adaptive vsync. Hopefully this also works on the cards where the old setup did not.

Changes to the contrast/brightness/gamma formula for both hardware and shader gamma correction. Mainly makes a correction with the shader version where contrast/brightness being negative values would clip them inappropriately.

- changed the license of the OpenGL renderer to LGPL v3.
...
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

- replaced GLEW with GLLoadGen for GL access. This allows to have a header that only contains what's actually required, namely OpenGL 3.3 plus glBegin and glEnd which are the only compatibility functions needed for the fallback render path.
...
GLEW has two major problems:
- it always includes everything, there is no way to restrict the header to a specific GL version
- it is mostly broken with a core profile and only works if all sanity checks get switched off.
