ui: use libexpoxy libepoxy does the opengl extension handling for us. It also is helpful for trouble-shooting as it prints nice error messages instead of silently failing or segfaulting in case we do something wrong, like using gl commands not supported by the current context.

opengl: add shader helper functions. Helper functions to compile, link and run opengl shader programs. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> 2015-04-24 07:48:45 +02:00
opengl: move shader init from console-gl.c to shader.c With the upcoming dmabuf support in qemu there will be more users of the shaders than just console-gl.c. So rename ConsoleGLState to QemuGLShader, rename some functions too, move code from console-gl.c to shaders.c. No functional change.

opengl: add flipping vertex shader Add vertex shader which flips the texture upside down while blitting it. Add argument to qemu_gl_run_texture_blit() to enable flipping.
