[vtkusers] How to use Hardware acceleration in Windows?

[de Boer Ingo]

Hi Carlos,

as far as I know, you have hardware acceleration by default.
Except, if you have disabled it in the windows system settings.

And there is no need in using a HDC directly. Just look at the
sample, like Medical1.cxx. VTK can do all the window stuff for you.

greets
