Function to create evenly spaced tickmarks for tachometer or speedometer display. Function uses sprites positioned on screen, and after you run the code, just do a print screen and paste it into your favorite art program.
Can control the total rotation of the tickmarks, the start location of the tickmarks, and the number of major ticks, up to 16.(counting zero).
I needed to do this because I want to make my own textures for the 3D speedometers/tachometers.
