Better frame capture backend

[jeffijoe]

The current GDI+ implementation leaks like hell, so would be nice with a DirectX backend instead.

Any help?

hmm, i can't help you yet. but thanks for your free software.

Will see if I have time to work on this, seems the project has gone a little cold. DXGI might be an option.

@jpc0 that'd be cool!
