jan c7f551b0b7 Use complex number representation for vertex coordinates,

ie. (x, y) becomes x + iy. This gives a bit of a speedup
over repeating stuff for multiple arrays, and lets you
keep using the numpy +- operators (unlike structured
numpy arrays)

float_raster README

float_raster is a Python module for accurately drawing polygons onto non-uniform rectangular grids

float_raster calculates pixel values with float64 precision and is capable of drawing on grids with variable pixel widths and heights.

Installation

Requirements:

python 3 (written and tested with 3.5)
numpy

Install with pip, via git:

pip install git+https://mpxd.net/gogs/jan/float_raster.git@release
