Various tools for calculating resolutions and ratios, originally written in python but ported to c++.
RatCalc: Takes a ratio and a single x or y value of a resolution and outputs the equivilent resolution based on the data given.
ResCalc: Takes a resolution and gets the ratio of it.
CropCalc: Takes two resolutions and then tells you how much you have to crop from the top and bottom/left and right in OBS or a video editor.
