Hi Dave & Andy,
I think we have a disagreement here about what SCALED types should be.
As I understood it SCALED types should be represented as integers in memory,
but when loaded into a shader converted to floats in the range 0..2^n (in
opposite to normalized types), and that's how I used them in g3dvl.
I also added code to r600g to support those types as textures and render
target, but this code got removed before merge because I figured out why
working with normalized textures/render targets didn't got the expected
results.
@Andy: The attached patch should fix your issue, but I will delay committing it
until we have figured out how SCALED types should be really handled.
