wayland::output_transform - transform from framebuffer to output
Contents
Detailed Description
transform from framebuffer to output
This describes the transform that a compositor will apply to a surface to compensate for the rotation or
mirroring of an output device.
The flipped values correspond to an initial flip around a vertical axis followed by rotation.
The purpose is mainly to allow clients to render accordingly and tell the compositor, so that for
fullscreen surfaces, the compositor will still be able to scan out directly from client surfaces.
