Heavily improved mandelbrot plugin: (1) Calculation now uses 64bit fixed point arithmetics to allow zooming in way further before the precision barrier will hit. Added asm-optimised 64bit multiplication routine for SH1; more than twice as fast as what gcc produces. (2) Precision is dynamically selected based on the zoom level, low zoom factors still use 32bit for speed. (3) Maximum number of iterations is adapted to the zoom level. You can still increase / decrease it while staying at a zoom level. (4) Panning only recalculates the scrolled-in part of the screen -> way faster panning.
