-/* Blend Mode goal:
- *     First multiply the foreground and background and then mix the result
- *     of that with the background based on a opacity value.
- *
- *     result = background * foreground * opacity + background * (1 - opacity)
- *            = background * (foreground * opacity + (1 - opacity))
- *                           <------------------------------------>
- *                                 computed in this shader
- *
- * Afterwards the background and the new foreground only have to be multiplied.
