Max image resolution as default #585

It took me some time to finally discover why my OCR results were totally awful. By default, resolution is 100dpi. This doesn't make sense, please set it to 600dpi instead, or whatever is max resolution.

Raster images generally don't contain any dpi information, so 100 actually just a scale factor in that case (admittedly I should rename the tooltip accordingly). For PDF documents, resolution is 300 dpi by default.
