I've added Managed Shader support in the package org.newdawn.slick.shader. To create a test class, I need an example vertex and fragment shader. Anyone?

liam, please stopp getting ahead on everything. I have a lot of problems with your system too. davedes system is also a lot cleaner and easier to understand imho

Here's some changes to my old class. It uses a hash map for convenience, like LibGDX, and adds a Shader inner class (which maybe will be moved to outer leve) for shader/program independency.

The releasing stuff is a bit messy. We'll have to add things like detachShader/attachShader if we really want it to be independent (and make shaders reusable over multiple programs).

Instead of abstracting the entry point to GL in the Program class, it should be done in Slick's SGL class. (Same goes for FBOGraphics.)

Maybe you really want to look and davdes implementation. I got it working without even reading the source or anything Want you want for sure is loading the source into a string using the ResourceLoader! That's the proper way for Slick2D loading.

Ah okay, I wasn't aware of it Keep on doing awesome stuff

Uniforms are only "active" in GLSL if the compiler can determine that they are actually used; so "time" (since you don't use it in the shader) isn't considered an active uniform and thus its uniform location (i.e. ID) returns -1.

I'll have to implement something to ShaderProgram like hasUniform or isUniformActive, as well as some error checking within setUniformXX to ensure that no null pointers are thrown.

Thanks for the find.
