Fix calculating the extent of clipping box (wxDC, GTK).

Browse Source 
While setting a clipping region there is necessary to intersect it either with current clipping region location if such region exists or with wxDC surface extents if no clipping region is set. This way effective clipping box will be always inside the wxDC surface. Effective clipping box can be an empty region.
Clipping box parameters are calculated and stored in logical coordinates.
