*
|
|
* - The size of the surface texture may not match the surface size anymore.
|
|
* Compositors must use the surface size only.
|

* - Compositors must call wlr_render_subtexture_with_matrix when rendering a

|
* surface texture with the source box returned by
|
|
* wlr_surface_get_buffer_source_box.
