* Add a readme so people know how the shadowmasks work. * Reorganize folder structure to be similar to other repos in the project like this. * Add retro (60's/70's) style CRT shadow mask which used a delta gun and round holes in the mask. * Add a variant of the dot mask above that is brighter which uses MYC colors for people with much darker LCD tv's with CE backlight dimming. * Add @wickerwaka's NECT slot mask he made awhile ago which resembles a popular style of shadow mask.

How It Works
Here's an example. If you wanted to make RGB dots that use this pattern:
Then you would make a file like this:
# w,h
6,4
# lut
4,4,2,2,1,1
4,4,2,2,1,1
2,1,1,4,4,2
2,1,1,4,4,2
These numbers correspond to the following r, g, b values like this:
r,r,g,g,b,b
r,r,g,g,b,b
g,b,b,r,r,g
g,b,b,r,r,g
