[r100]Blend shaders+Layer rotation

Upon rotating the layer, blend shaders assigned to sprites resize incorrectly and creates a hall of mirrors effect.

at a layer angle of 45, the width of the shader is double and the height is 0

It only happens to sprites that are not at angle 0

Arrows left+right to rotate the layer.

Squares have the 'darken' effect enabled. I've tested with several other blend modes but not all of them.

The square on the left is angled at 0 and is unaffected

middle is angled at 45

right is angled at 0.01

I have latest ati drivers, tried in chrome and ff.

Also I get these black rectangle artifacts where shaders overlap, or just at the edges of the screen.

It's not consistent however.. It was happening in the cap posted above earlier but has stopped now.

I have a feeling it's just me otherwise someone else would have pointed it out.

Nope, it happens for me too.

Should be fixed in r101, can you confirm?

Ashley yep it's working thanks

New bug though:

If you have a blend shader alongside a colour shader.

For example 'lighten', and 'set colour'

The shaders position seems to be clamped within the viewport
