WMCreateApplicationIconBlendedPixmap() to avoid confusion. This is because this function does generate a new WMPixmap from the available icon image by combining it with the specified color and you need to call WMReleasePixmap() on the generated pixmap after you're done with it. This is unlike the case of WMGetApplicationIconPixmap() where it just returns a pointer to the existing application icon pixmap that was set before and where you don't need to release it after you're done working with it. To avoid this confusion about when you need to release and when not, one is using Get (get existing, no release needed), while the other is now using Create (generate a new pixmap, release required) in their name. Since this change was made to a function that was just added to the API in the previous commit, no modification is needed to the existing applications that use WINGs.
