 To transfer the contents of the surface to another display of the same pixel format, the following API can be invoked:
 
 ```c
-bool qp_surface_draw(painter_device_t surface, painter_device_t display, uint16_t x, uint16_t y);
+bool qp_surface_draw(painter_device_t surface, painter_device_t display, uint16_t x, uint16_t y, bool entire_surface);
 ```
 
-The `surface` is the surface to copy out from. The `display` is the target display to draw into. `x` and `y` are the target location to draw the surface pixel data. Under normal circumstances, the location should be consistent, as the dirty region is calculated with respect to the `x` and `y` coordinates -- changing those will result in partial, overlapping draws.
