[Laszlo-user] Image stretching problem

[bs .]

Unfortunately, it didn't have any effect.  I made a small test program to
show it clearly.

You can see the code below in operation at:
http://mtterra.com/image_test.htm

It starts with the small image, just double click and it will toggle the
large image then small.  The small image is 640x480.  The large one is
2048x1536.

I have read on other threads that unload() might have some issues.  I
noticed it doesn't really free my large images.  Very noticable since my
firefox usage jumps from 100M to 130M and doesn't drop.  I'm still working
on that one, probably a code error but never know.  I haven't checked it
against 3.3.3.

Cheers,
Bruce
