Transparent fill overwrites any previously drawn pixels on the overlay layer,
but not drawing the fill leaves the previous pixels unchanged.
Drawing filled rectangles is slower than drawing unfilled rectangles.

Corner Marker Fields
– Field Type 3
Corner Marker Fields are used to indicate a region of interest in the video.
The Corner Markers are drawn around the outside of the region specified by
Coordinate A (top-left) and Coordinate B (bottom-right).
The Width parameter of the Graphic Field sets the width in pixels of the lines that
make up the corner markers, and the Length parameter of the Graphic Field sets
the distance in pixels that the lines extend from the corner.
Corner Markers are drawn in the line color (as specified by the SnnRrrr, SnnGggg,
SnnBbbb, and SnnAaaa commands).
By default four corner markers are drawn. It is possible to suppress the corner
markers individually using the SnnKcs command. The letter s represents either 1
to suppress the corner marker, or 0 to enable it. The letter c represents a letter
that indicates which corner marker is being referenced as follows:
A = top-left
B = bottom-left
C = top-right
D = bottom-right
For example the command S1KB1 will suppress display of the bottom-left corner
marker of Graphic Field 1.
Note:
If the width of a Corner Marker is made too large relative to its length, the Corner
Marker will appear as a square.
The x position for coordinate A should be less than that of coordinate B and the y
position for coordinate A should be less than the y position for coordinate B. The
DX-2200 will automatically reverse the x and/or y coordinates when drawing the
corner markers if they are set incorrectly.
