FS#10865 - Mandelbrot: Yield buttons during painting of the fractal

In Mandelbrot demo application, increasing iteration depth causes slow painting of the fractal. The painting function yields during the painting, but does not responds to user interactions. If you want to move / zoom in/out the fractal, you have to wait until drawing ends.

This implementation yields the buttons during painting (each 0.25 sec).

Currently, pressing a button redraws the entire screen. This can be optimized further, but it is better in terms of usability than current implementation. I don’t see a reason for it to hurt drawing performance much.

I would like to get some more comments for this so I know if its ready to be committed,

I’d prefer something like this: check tick before calling check_button() and check_button() returns button code.
