Added dynamic scaling for vertical icon spacing.
This means that on startup D-Pixel will adjust the spacing between icons in the vertical dimension to fit into the screen (minus the taskbar). So for users with a double size taskbar it won't cut off any part of the GUI. Also at lower screen resolutions where the taskbar is a bigger proportion in size compared to at higher screen resolutions, it will still scale to fit ok in the screen size.
There is also a difference in the GUI size between the original version of D-Pixel and the new version. The old version only had space for 9 icons vertically in the main tool options (a legacy of supporting 1024 x 600 for netbooks). Whereas the new version has space for 15 icons vertically. This gives me much more room when designing the GUI panels, although of course it's never enough for some tool options!
