Mandelbrot: GCC2 fix.

Mandelbrot: Implement subsampling

* Added subsampling. This makes the render look less noisy and generally nicer.

Mandelbrot: Improve thread handling code.

* Application is now much more stable and less likely to crash
* Almost all communication to render threads is done through semaphores.

Mandelbrot: Implement incremental rendering and other improvements.

* Incremental rendering allows the user to see how the render is progressing.
* Can move to a new location before the render fin

Mandelbrot: Implement incremental rendering and other improvements.

* Incremental rendering allows the user to see how the render is progressing.
* Can move to a new location before the render finishes. Render will automatically restart at the new location.
* Multi-threaded rendering now renders from a horizontal line in the center, giving a better experience.
* Improved behavior for scrollwheel zooming. Now zooms with the mouse as the origin, as is the standard behavior in other applications such as map viewers.
* Added lots of TRACE statements internally, which can be turned on in the code for debugging.

Mandelbrot: Scrap the old app, initial workings of a new one.

Based upon a HTML5 fractal engine by @kerwizzy (relicensed as MIT and copyright
assigned to Haiku, Inc. with permission from the author). Hacky and a mess,
but it works, and has the potentiality to be much nicer than the previous
Mandelbrot app.

Already supports rendering & zooming in, but has hacks all over the place.
