Improved display of focus points that have no dimension (focus pixel)

[capricorn8]

For focus pixel points (as used by e.g. Olympus, Panasonic, Fuji) it would be nice for the user to have the ability to choose how the focus point is displayed - small box (like OM Workspace does) or bigger box with a center dot representing the focus pixel. A selection of different colors could help to better recognize the focus point symbol on certain images, e.g. avoid a red box on a red subject.

A selection of three different sizes (small, medium and large with center dots) and three different colors (red, green, blue) will be offered to choose from. Color choice is currently limited to Windows only. For use on macOS this requires creation of icon sets in blue and green colors.
