Image blend

Explanation
By default, the blend color is c_white. A blend color of c_black will make the image completely black. Other values will colorize the whole sprite depending on the red ,green and blue values used. Normally, when blending an image, its color will always be darker than the original color. But you can get other effects by changing the blend mode.

The image_blend variable was introduced in Game Maker 6.0 and is a variable you can only use when you register your copy of the program.
