1) go to the http://www.cdrom.com/pub/png/png-MagnoliaAlpha.html with
   NETSCAPE4.61 and check the png image. Image is OK ( aka beatifull )
2) go to the same URL from above with mozillaM8 and the image is BAD
   Blue background of the image (sky) is wrong. Instead of being blue it
   uses a color and texture of the page itself.

I would like to mail to you two "screenshots", a GOOD one and a BAD one,
but I do not have your e-mail address. Please let me know where I can
mail two GIF files

Sincerely

Instead of mailing the image, display this bug in bugzilla, press the "Create a
new attachment" link, and attach your screen shots to the bug. This way,
everyone can see the screen shot, not just Pam.
Pam, might this perhaps be a duplicate of 3013? (alpha channel not supported)

uh.
This isn't a bug. seriously.
The alpha channel means the textured background
should show through. Seeing the 'sky' background means
that alphachannel is not implemented.

Alphachannel is implemented with a _THRESH HOLD_.
I have a full 8bit (graduated) alpha channel implementation
on windows for non scaled images. I don't want to check it
in until I find out why the scaled images are going wrong.
