Hi, Matteo Bruni.

I make some time googled about wine shader model3.0 constant register limit
and traced dlls/wined3d/shader.c. It seem like wine forece limit sm3.0 max
number of float constant registers to be 256, my video card(Mobile Intel GM45
support dx10/sm4.0) does have 4096 registers detected by
gl_info->limits.glsl_ps_float_constants. I don't know why.

At same time i googled some information about even if wine forced sm3.0
limit 256 float constant registers, most dx9/sm3 app may not practicality use
all of them though wined3d shader bytecode like 'def c783...'.

So i think does wine could reorder to use the float constant registers array
like 'def c0 ~ def c255' mapping the hlsl constant from app one by one, to
avoid using more than 256 registers?
