Tints: Add blending modes Screen, Overlay, and Hard Light, as opposed to the default Multiply. This value is encoded in bits 6 and 7 of the "flags" parameter. In other words, calculate your flags besides these modes, then bitwise OR the resulting value with:

0 - Multiply
64 - Screen
128 - Overlay
192 - Hard Light

Note: These will likely look terrible when combined with the Colorize flag, because of the nature of the Colorize flag.
