Thank you all!
Well here are some keyboard controls for navigation:
Arrow keys: move around
PageUp: zoom in x2
PageDown: zoom out x.5
Home: Increase resolution (slower)
End: Decrease resolution (faster)
Esc: quit
@Stan: The resolution control works by increasing/reducing the maxit variable. Thanks for suggesting it.
To up performance I reverted to assembler for the core calculation. It makes a big difference in speed by eliminating a lot of memory accesses.
Would anybody like to add a coordinate/zoom factor display ?
