Simple testing :)

can you add border tests in future:

 hret = IDirect3DDevice9_SetVertexShaderConstantB(device_ptr, 
MAX_VSHADER_CONSTANTS  - 4, bool_in, 4);

 hret = IDirect3DDevice9_SetVertexShaderConstantB(device_ptr, 
MAX_VSHADER_CONSTANTS  - 2, bool_in, 4);

I'm interested to see how windows handle that :)

Sure. This test is only for checking if the values don't get
overwritten though, so we want to use safe indices here :-)

Thanks for the test and bugfix - I'll submit some of my own, starting 
with the mipmaps patch.

MAX_VSHADER_CONSTANTS is most likely the wrong border for boolean and 
integer constants.
Shaders 3.0 support a max of 16 integer and 16 boolean constants [ so is 
the limit the max for all shader versions? ]

No, D3D8 need to support 96 float integers :)
