More blend modes

Specifically subtract so I can clear the screen with alpha (motion blur) and not leave artefacts, but others would allow for some really lovely effects.

    Added blend modes:

    • subtractive (subtract foreground from background)
    • inverse-subtractive (subtract background from foreground)
    • multiplicative

    I adopted the naming scheme, but it should be changed to:

    • alpha
    • add
    • subtract
    • inverse-subtract
    • multiply
