Return the next buffer that should be composited/rendered.
- Parameters
-
| [in] | user_id | An arbitrary unique identifier used to distinguish separate threads/monitors/components which need to concurrently receive the same buffer. Calling with the same user_id will return a new (different) buffer to that user each time. For consistency, all callers need to determine their user_id in the same way (e.g. always use "this" pointer). |
Implemented in mir::scene::BasicSurface, mir::test::doubles::FakeRenderable, and mir::test::doubles::StubRenderable.

Transformation returns the transformation matrix that should be applied to the surface.
By default when there are no transformations this will be the identity matrix.
- Warning
- As this functionality is presently only used by mir_demo_standalone_render_surfaces for rotations it may be deprecated in future. It is expected that real transformations may become more transient things (e.g. applied by animation logic externally instead of being a semi-permanent attribute of the surface itself).
Implemented in mir::scene::BasicSurface, mir::test::doubles::FakeRenderable, and mir::test::doubles::StubRenderable.
