The swf_addcolor() function sets the global
add color to the rgba
color specified.
This color is then used (implicitly) by the
swf_placeobject(),
swf_modifyobject() and the
swf_addbuttonrecord() functions. The color of
the object will be add by the rgba
values
when the object is written to the screen.
Note: The
rgba
values can be either positive or negative.
