# File : qtfractal.py
# Date: Sun Dec 05 22:53:44 PST 2021
#
# Usage:
#
# - Click and drag mouse to create zoom box
# - Hold shift while creating zoom box to drag it around the screen
# - Use Command+Mouse Click to center the picture at the current zoom
# level at the click location
# - Use ctrl-Mouse click to zoom out
#
# Note : mpfrnative is a much faster high precision implementation than
# hpnative
#
# TODO:
#
# - passing precision in mpfrnative
# - delete / reset on list
# - clean up status / debug printing end to end
# - write raw calculations from C to binary file
#
# Done :
#
# - add a back button to get to the last n pictures
# - get mpfrnative working fully (tested to -100, colors, samples, etc)
# - support passing max iter in ldnative and mpfrnative
# - ability to save current config (should be easy now that we have
# - waypoint preview
# context)
# - preview radio button for snapshot window
# - add a "reset" button to get to the initial config
# - get julia sets plugged into UI
# - implement sampling with julia sets
# - Fix mandeldistance
# - Add support for max-iter
# - Get colors working
# - increase number of sample points per pixel from UI
# - center on current mouse location picture if mouse pressed some key
# held
#
# Really nice colors : 0, .19, 1.0
