示例1: main

* Blank the screen. This also blanks the one-pixel region between
* the bottom of the fractal and the top of the elapsed time indicator
* below.

System::paint();
/*
* We use STAMP mode in a special way here, to do (slow) true-color
* rendering: The framebuffer is simply set up as an identity mapping
* that shows each of the 16 colors in our colormap. Now we can put
* a row of 16 pixels directly into the colormap, and render the screen
* using 1024 of these little 16x1 pixel "frames".
*
* Clearly this is really slow, and this technique is unlikely to be
* frequently useful, but it's a fun parlour trick :)

* now to call finish(), we're allowing the calculation above
* to run concurrently with the cube's paint operation.
*
* Note that our "frames" are actually just tiny pieces of the
* screen, so we need to avoid the default frame rate limits
* in order to render at an at all reasonable rate. This is
