I've been working a bit with a orthorgaphic camera, and wanted to do a little
tag for my images, so ok. I go ahead. but, this doesn't take much of place on
the image, but there still is a MAJOR time difference between renderspeed for
ALL the image. I wonder why this is?
ok, there is transparency involved, but I didn't expect so big differences.

here are some times with a bit more advanced image than the one I include. This
one is the same tag, but has a image map and a heightfield in it, that really
changes other rendertimes. but I think it is speaking enough.
	time(s)		Memory(b)
merge:	3724		30241894
union : 380 		30241894

render settings :
	antialias off

	height = 1221
please keep the ratio :-)

Did you try to manually bound it? Sometimes helps a *lot* .

I didn't try in this case, I will.
