Michael Niedermayer 04bb26e3ee mandelbrot: add dither to convergence & mincol colorings.
This avoids banding artifacts.
Note, low end TFTs still show some banding.

Stefano Sabatini 2b1a4c5b34 amovie: avoid crash in amovie_request_frame() if no samplesref is available
The crash occurrs when a frame is successfully decoded, but no decoded
data is immediately available (typically happens with ogg/vorbis).

Giorgio Vazzana e555119c73 mandelbrot: correct and simplify the formula used in NORMALIZED_ITERATION_COUNT
Use log(sqrt(mb->bailout)) instead of log(mb->bailout) because mb->bailout represent
the bailout radius squared, and then simplify the two sqrt().
This is also slightly faster.
