Three components are involved in displaying device content on screen:

• a window
• a renderer
• a texture

Originally, all three were handled by sc_screen.

Commit 051b74c later extracted the renderer and texture into a separate component, sc_display.

However, the split was a bit awkward because the window size and rendering location were managed by separate components.

Move rendering back to sc_screen, keeping only texture management separated in sc_texture.
