Routine Description:
Overlay text onto the synthesized image. Clip to fit the image

Arguments:
LocX -
The X location on the image to begin the overlay. This MUST
be inside the image. POSITION_CENTER may be used to indicate
horizontal centering.
LocY -
The Y location on the image to begin the overlay. This MUST
be inside the image. POSITION_CENTER may be used to indicate
vertical centering.
Scaling -
Normally, the overlay is done in 8x8 font. A scaling of
2 indicates 16x16, 3 indicates 24x24 and so forth.
Text -
A character string containing the information to overlay
BgColor -
The background color of the overlay window. For transparency,
indicate TRANSPARENT here.
FgColor -
The foreground color for the text overlay.
