Functions | |
| void | AddRenderItem (RenderItem *item, int layer) |
| Adds a new RenderItem to the world list of a Layer. | |
| void | ClearRenderItem (RenderItem *item) |
| Makes an item no longer visible until the next PlaceRenderItem() call on the item. | |
| void | ForceDirtyFrame () |
| Set the dirty flag to force the renderer to perform a partial redraw for the next frame. | |
| void | ForceRenderAll () |
| Force everything to be redrwan for the next frame. | |
| void | GenericSurfaceRenderer (SDL_Surface *dest, RenderItem *item) |
| Renders a surface pointed to by item->data. | |
| void | PlaceRenderItem (RenderItem *item) |

| Removes a RenderItem from a Layer. | |
| void | Render () |
| Renders a frame. | |
| void | RenderClearStates (Uint8 numStates) |

| Bool | RenderInit (Uint16 numRects, Uint8 numStates) |
| Initalizes the rendering system. | |
| void | RenderUninit () |
| Uninitializes the rendering system. | |
| Bool | RenderWillRenderAll () |
| Tells if the next call to Render() will render an entire frame rather than just a changed portion. | |
| Bool | ResizeWindow (Uint16 w, Uint16 h) |
| A utility function for resizing the program's window. | |
