Add multiply, invert and screen methods #15

Open benjamminf opened 10 years ago

benjamminf commented 10 years ago

Added the blend modes multiply and screen as well as a method to invert the color. Test cases provided.

Usage:

Spectra(...).multiply(...);
Spectra(...).screen(...);
Spectra(...).invert();

Have a fair few more blending modes to go but thought I'd go ahead and commit these.

I should be able to merge this when you fix those two comments.
