Subject: [PATCH] wined3d: Use the ARB native constant limit in the GLSL-ARB
 constants quirk.

Geforce 8 and Geforce 9 cards support 256 env and 1024 native
constants. 1024 is the hardware limit we want to use if we overwrite
the GLSL reported value with the ARB value on Mac OS (because Mac OS
reports more constants than supported by HW on some cards).
