Changes

Add ShaderUtil.isComputeShaderSupported() and ComputeShader01GL4ES31 demo

JOGL Compute ShaderCode demo using OpenGL 4.3 or ES 3.1 core profile features.

The compute shader fills tuples of vertices + color attributes in a VBO buffer,
passed directly to the vertex-shader w/o leaving the GPU.
