One simple approach is to use an access type for allocation, but use renaming to
maintain compatibility with what you've already written.
procedure Test_Image is
Image_a : access Image_t := new Image_T(1..1024, 1..1024);
Image : Image_t renames Image_a.all;
FillColor : constant Color_T := (0, 0, 0);
begin
Fill(Image, FillColor);
end Test_Image;
I am not in front of an Ada compiler right now so the syntax may be slightly
off, but I hope the basic idea is clear
