Node definitions for a non-standard Programable Shaders extension

Classes

class FloatUniform( Node ):
Uniform (variable) binding for a shader
The FloatUniform is the base class for FloatUniforms, that is, there are FloatUniform1f, FloatUniform2f, FloatUniformm3x2, etceteras Node-types, but not a FloatUniform node-type.

attributes
define the attribute pointers which feed the shader, the individual attributes may share a buffer or define one per attribute
indices
if present, node defining index array to be used to index into buffers, will be uploaded to an element buffer
uniforms
Uniform nodes which are bound/updated on the shader before rendering this geometry, binds to the shader's location == to the uniform's name.
slices
slices of the array to render, if not specified then we'll render the whole data-set
