Enumeration of the blending factors
The factors are mapped directly to their OpenGL equivalents, specified by glBlendFunc() or glBlendFuncSeparate().
Enumeration of the blending equations
The equations are mapped directly to their OpenGL equivalents, specified by glBlendEquation() or glBlendEquationSeparate().

}Blending modes for drawing
Construct the blend mode given the factors and equation.
This constructor uses the same factors and equation for both color and alpha components. It also defaults to the Add equation.
val alpha : tCommonly used blending modes
Blend source and dest according to dest alpha
val add : tBlend source and dest according to dest alpha
Add source to dest
val multiply : tAdd source to dest
Multiply source and dest
val none : tMultiply source and dest
Overwrite dest with source
