As a follow up to cover the small details-
The gun sight bitmap probably should be the same size as the main 2D panel bitmap. Because you usually won't know where the VC poly is located a full sized bitmap will catch it somewhere anyway. That is, if in fact the image needs a polygon to match with - I am totally unclear on this part.
The bitmaps used for panels are a regular windows bitmap format BUT it must be 256 colors or less. Pure black RGB 0,0,0 will be translated as clear, so no alpha channel is required.
