softpipe: set a lower minimum clamp value for texture coordinate border clamp
The value of -0.5f is not small enough to produce negative coordinates, so lower the minimum clamp value to -1.0f. This fixes a number of tests from dEQP-GLES31.functional.texture.border_clamp.* Signed-off-by: Gert Wollny <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
