[WIN32SS] Handle panning in LDEVOBJ_bProbeAndCaptureDevmode

Browse source 
- search a graphic mode corresponding to real screen resolution (not virtual panning one)
- when capturing the selected mode, copy from input the virtual panning resolution
- when searching the best mode, also try without panning
