* When enabling viewporter, compositors need to update their rendering logic:
|
|
*
|
|
* - The size of the surface texture may not match the surface size anymore.
|
|
* Compositors must use the surface size only.
|
|
* - When rendering a surface texture, compositors should use
|
|
* wlr_surface_get_buffer_source_box() to get the source rectangle and crop
|
|
* the texture accordingly.
