CSP1150 A1: modified sysout debug to show minX, minY, maxX, maxY while dragging mouse
CSP1150 A1: pixel max-min values now stored, need to be converted to grid ratio
CSP1150 A1: adding methods to set and reset zoom, also changed order to minX, minY, maxX, maxY, makes more sense
CSP1150 A1: fixed methods to convert pixelzoom, added mandelbrot overrides
CSP1150 A1: zoom in/out for annulus implemented, not zooming to the right area though, will need to look at the conversion
CSP1150 A1: zoom and reset buttons now work for both annulus and mandelbrot, need to fix miny maxy and maybe draw perfect square instead of rectangle
