When comparing a large and a very small image and then activating the grid, XnView crashes.

To reproduce:
1. Start XnView
2. In XnView browser select a large i(e.g. 2000x2000) and a small (e.g. 100x100) image file.
3. Select "Tools > Compare..."
4. In Compare dialog, activate "Grid".
5. Zoom in/out
:arrow: XnView will crash :bug:

XnView 0.84 MP x32

Problem is not the Compare dialog, it's the grid which causes problems when displaying small image.

An even easier way to reproduce:
1. In XnView, open a small image (e.g. 100x100) in View mode
2. Activate Grid
3. Zoom out
:arrow: XnView crashes

EDIT:
- I've played around a bit. The crash seems to occur with any image smaller than about 400x400 pixels.
- XnView Classic 2.39 doesn't crash in the same scenario. :)
