A Compositor variant that supports mapping tiles into CPU memory.

Required Methods

fn map_tile( &mut self, device: &mut Device, id: NativeTileId, dirty_rect: DeviceIntRect, valid_rect: DeviceIntRect ) -> Option<MappedTileInfo>

Map a tile’s underlying buffer so it can be used as the backing for a SWGL framebuffer. This is intended to be a replacement for ‘bind’ in any compositors that intend to directly interoperate with SWGL while supporting some form of native layers.

fn unmap_tile(&mut self, device: &mut Device)

Unmap a tile that was was previously mapped via map_tile to signal that SWGL is done rendering to the buffer.

fn lock_composite_surface( &mut self, device: &mut Device, ctx: *mut c_void, external_image_id: ExternalImageId, composite_info: *mut SWGLCompositeSurfaceInfo ) -> bool

fn unlock_composite_surface( &mut self, device: &mut Device, ctx: *mut c_void, external_image_id: ExternalImageId )
