TO DO

The following are some ideas for the future:

* Polygons With Rounded Corners *

Polygons with rounded corners would be difficult, but doable.  It has become
quite difficult to get working so far.  I haven't given up.

* Completely accelerate all primitive drawing

Currently only some functions are C code accelerated.

The slowest will be addressed first.

* Incorporate all methods that need Imager to use their own C code, so Imager
* is no longer needed.

Imager's lack of support for RGB565 is the reason for this need.  The slight
increase in speed won't hurt either.

* Make double-buffering the default for 16 bit and make it seamless. *

It's close right now
