Add cogl_texture_pixmap_x11_new_left() and cogl_texture_pixmap_x11_new_right() (which takes the left texture as an argument) for texture pixmap rendering with stereo content. The underlying GLXPixmap is created using a stereo visual and shared between the left and right textures. Reviewed-by: Robert Bragg <robert.bragg@intel.com>
