simple one line gradient
working on raster printer

raster driver takes png filename from command line
added picture in higher res 128x128
fixed drawing always missing first column
fixed bug with missing iidexes
we do not waste time for coming back to column 0
removed drawing of dots from device simulator
raster try
only one zigzag per pixel
randomized raster rendering, damn monads
higher spike count
inverted colors and decreased number of random spikes to speed up printing
