- <p>
- Makes sure the given
- list of rectangles is updated on the given screen. The rectangles must all
- be confined within the screen boundaries (no clipping is done). <p>
- This function
- should not be called while <b>screen</b> is <i>locked</i>. <p>
- <blockquote><b>Note: <p>
- It is adviced to call
- this function only once per frame, since each call has some processing
- overhead. This is no restriction since you can pass any number of rectangles
- each time. <p>
- The rectangles are not automatically merged or checked for overlap.
- In general, the programmer can use his knowledge about his particular rectangles
- to merge them in an efficient way, to avoid overdraw. </blockquote>
