raganmd fixes to resolution error - added exports to manually set resolution for
all GLSL tops - a bit of a bummer, but the right way to handle this I
think.

GLSL 2D Tutorials by Uğur Güney

From Uğur:

by Uğur Güney. March 8, 2014.

Hi! I started learning GLSL a month ago. The speedup gained by using GPU to draw real-time graphics amazed me. If you want to learn how to write shaders, this tutorial written by a beginner can be a starting place for you.

Please fix my coding errors and grammar errors. :-)

Getting your bearings with GLSL can be a bit of a rodeo when you're first getting started. Uğur's 2D tuts were a huge help to me when I was first getting started, and they often show examples that are a little more granular than The Book of Shaders.

Hopefully this set of examples will help you get started and get your gl bearings here in Touch.

When possible, I've copied the examples as faithfully as possible. What that means is that there may be better ways to approach some challenges - but what you'll find here is as close to the original tutorial as I can manage.
