[Feature request] Zoom to 100% while holding left-click

[sueskind]

Left-clicking and holding the mouse in "fit mode window" (Key: 1) does currently not have any functionality. A great feature of the FastStone Image Viewer (Windows only) is that clicking & holding zooms the image to 100% (as pressing Key 3 does currently in qimgv) and then the user is able to drag around the whole image.

This would help a lot for e.g. finding sharpness differences between two similar images. Currently one has to press 3 to zoom to 100%, then drag around which can be tedious for high resolution photographs.

Furthermore, it would be helpful if the arrow keys are still usable to go through the images while holding the left mouse button.

Great feature I would say. Sounds like an instantly observing mode.
