This function populates a list of VID s that match the contents of a
specific rendertarget at the time of calling. It can be used to perform
certain mass-actions without manually maintaing a list of vids collected at
allocation time. If rtvid is not specified, the current default
attachment will be used.
function rendertarget_vids0()
local a = color_surface(8, 8, 255, 0, 0);
local b = color_surface(4, 4, 0, 255, 0);
for i,v in ipairs(rendertarget_vids()) do
show_image(v);
print(a, b, v);
end
