In the first phase we collect a list of simple operations (copying
textures and filling rectangles.)
In the second phase we send this list to the graphics API to be
executed.
As part of this, we also remove the use of scissors.
This involves many subsystems:
- config:
- allow setting the connector scale
- allow setting the cursor size
- cursors:
- load server cursors for all requested sizes and scales
- wl_surface:
- track the output the surface belongs to
- send wl_surface.enter/leave
- wl_output:
- implement wl_output.scale
- text:
- pre-render texts for all used scales
- renderer:
- properly align scale textures and rectangles
- wp_fractional_scale:
- new interface for fractional scaling
