Add screen magnifier This adds a screen magnifier which can be controlled with the `ZoomIn` / `ZoomOut` and `ToggleMagnify` actions. It scales up part of the rendered framebuffer so the magnification may end up looking blurry depending on the magnification scale.

backend/drm: Implement support for renderer loss recovery This implementation is nearly identical to Sway's, except that it also reloads the configuration, to spur on reloading the server-side decorations. v2: Fix style. v3: Add a reset to the magnifier. v4: Oops, restructure reset handler a bit. v5: Commit the magnifier reset immediately, before freeing the lost allocator and renderer. v6: Also check for failed render pass, which may return NULL. v7: Add a second NULL test, just in case. 2024-07-17 17:13:51 -07:00			`void magnify_reset(void);`
