void GPU_vertformat_deinterleave ( GPUVertFormat * format)

Make attribute layout non-interleaved. Warning! This does not change data layout! Use direct buffer access to fill the data. This is for advanced usage.

De-interleaved data means all attribute data for each attribute is stored continuously like this: 000011112222 instead of: 012012012012

Note
This is per attribute de-interleaving, NOT per component.

Makes vertex attribute from the next vertices to be accessible in the vertex shader. For an attribute named "attr" you can access the next nth vertex using "attr{number}". Use this function after specifying all the attributes in the format.

NOTE: This does NOT work when using indexed rendering. NOTE: Only works for first attribute name. (this limitation can be changed if needed)

WARNING: this function creates a lot of aliases/attributes, make sure to keep the attribute name short to avoid overflowing the name-buffer.
