2017-10-17opengl: add flipping vertex shaderGerd Hoffmann1-3/+9
Add vertex shader which flips the texture upside down while blitting it. Add argument to qemu_gl_run_texture_blit() to enable flipping. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20171010135453.6704-4-kraxel@redhat.com
2017-10-17opengl: move shader init from console-gl.c to shader.cGerd Hoffmann1-9/+42
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.

2015-10-08shaders: initialize vertexes onceGerd Hoffmann1-5/+26
