Display reticle in virtual coordinates

[szapp]

The reticle is drawn using physical pixels. This results in very tiny reticles in screen resolutions larger than full HD. Instead use virtual screen coordinates.

It might be a good idea to give the end user more control. Instead of setting the reticle to pixels or virtual coordinates (size relative to screen resolution), the INI setting may be a pixel scaling factor, e.g. a setting of one would leave the reticle at 64 pixels width, a value of two would result in a size of 128 and so on.
