[TYPO3-core] RFC: Bug #7817: Transparent PNGs do not work in IE 6

Hi all,

This is a SVN patch request.

Type: bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=7817

Branches: 4.2

Problem:
IE6 is too stupid to handle alpha channel PNGs (and basically everything 
else that's fun)

Solution:
use Javascript to apply Microsoft's special filter where this works. 
However, there are places where this didn't work (background images like 
the arrows in the module menu with t3skin). After trying to make this 
work for two days now (together with Steffen) I give up... I've added 
the affected images in a new folder /typo3/gfx/ie6/ so that we know that 
we can safely remove them at some point. These images are used through 
an additional stylesheet for IE6 in t3skin.

Notes:
unpack the zip with the images in /typo3/gfx/ and apply the patch.


Ingo
