That was a pretty simple change, but when I re-ran the tests on Windows to be 
sure they work the ATI2N test failed.

On Nvidia drivers ATI2N has 4x4 blocks, which makes sense, but if you violate 
that the driver returns E_INVALIDARG instead of D3DERR_INVALIDCALL. Oh well. 
On AMD, ATI2N has 2x2 blocks, which doesn't make sense to me. When I ran the 
tests on Windows the last time the 1x1 "blocks" locked fine. I couldn't 
reproduce that even with the last version of my patch.

I've changed the test and implementation according to those results, but 
before I resubmit them I'll test a few more Windows machines(especially dx9 
and xp based ones).

What's changed:
*) block_size removed, this was unused
*) Improved messages, print the pool
*) Use block_dimensions / 2 instead of block_dimensions - 1 to construct 
invalid blocks.
*) Adjusted test to 2x2 / 4x4 ATI2N block sizes
