	You can use the following test code to get something running quickly. Note you should use some better shader functions which print out an info log if you made an error in your shader code. Also note that GLES2 fragment shaders require precision qualifiers (lowp, mediump, highp) for floats. I used an #ifdef statement so the shader code works with both OpenGL and OpenGLES 2.

	You know what I just did? Yeah, I drew a triangle! Nope, you can't draw stuff like this in OpenGL ES 1.1, so how would one draw a triangle in ES? ~~Bare~~ with me while you read this if you don't understand it, I'll explain it in depth.

	== Introduction ==		== Introduction ==
	Unfortunately, the OpenGL ES takes away many of the functions that beginner programmers use. They do this, because a lot of those functions are plain rubbish for any high-end application. We're only covering ES 1.1 here, but the Pandora also supports ES 2.0, which, leaves you with a handful of functions, you have to do all of the matrix math on your own. Which can be really hard if you're not good at maths, I'll cover how to do that in a later tutorial. What you're learning here isn't just for the Pandora, you should use these new methods in your Windows/Linux code. These changes are being made to the core OpenGL too, so you're loosing all of this stuff soon enough. Which is silly, OpenGL is good because beginners can pick it up easily. But whatever, I'm not in charge.		Unfortunately, the OpenGL ES takes away many of the functions that beginner programmers use.
