[vtkusers] VTK 64 bit slow rendering on some studies

[EvilMax]

Problem is solved.

*Issue:* wrong VideoRAM amount detection. On my GTX260 VTK saw only 128M and
144M study rendered EXTREMELY slow when smaller ones were just Ok.

*Fix1 (main):* always build VTK with DirectX SDK on Windows! Don't be lazy -
download it and install! Not a problem that it is 1,2 Gigs of libs and
heared - it will guarantee correct VideoRAM size detection.

*Fix2 (working too - tested):* set actual information of VideoRAM in ray
casting mapper in code.
