[YAGGLER/SETUP/DEBUG CONTEXT]: creating a debug context will also create a stderr logger function. reworked a bit how the setup::opengl works (and updated the samples)
[YAGGLER/TEXTURE/OGL_TEXTURE]: removed a silly nvidia driver flood on mipmaps being unused on a texture without mipmaps.
[KLMB/YAGGLER/MATERIAL]: now build on clang. :)
[KLMB/SAMPLE/SHADER]: updated the test shader.
