The old Win3 labels were not without their limitations, that main one was no transparent background so you got the system color background which usually clashed with either image backgrounds or user selected background colors. This is a size efficient replacement that preserves the transparent background, can be placed over anything in the client area, it can be aligned with the normal DrawText flags and it uses a user defined fixed 2 color display, text color and shadow color.
The transient arguments are set in a normal argument list, the fixed arguments are set in a structure.
