increasing disparity search range to 512 #66

This would enable higher resolution images to be used, perhaps increasing precision/accuracy. Any pointers on how to go about it would be much appreciated! Thank you.

The same request here. Appreciate it if we can use other values (generally higher) for disparity than 64, 128, 256.

I implemented 512 disparity support on a branch of my fork: https://github.com/Sir-Photch/libSGM/tree/512-support

It seems to work properly, that is: the disparity images look fine. However, I had to make multiple changes to bit-widths of computations in the CUDA code and I cannot verify the correctness for it (yet?). The original test suite sgm-test works fine though.

If the maintainers of this project are interested, I'll gladly submit a PR.
