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.

Variants

_180

Flipped90

flip and rotate 90 degrees counter-clockwise

Flipped180

flip and rotate 180 degrees counter-clockwise

Flipped270
