More granular screen resize

[dmazan]

There are a lot of monitor sizes in various aspect ratios. HamClock looks great on a big HDMI monitor on a wall or other mount. But the package is only available in a limited series of screen sizes.

• Best would be able to configure HamClock for any horizontal and vertical resolution.
• Almost as good would be the ability to select a larger number of common screen resolutions, like 1920x1080.
• Slightly less good would be the ability to scale the HamClock screen independent of the system screen size or other applications.
• Good for me but maybe not globally would be instructions on how to create new screen sizes, assuming they require some rearrangement of components on the screen.
