[TYPO3-core] RFC: #14813: Install Tool uses deprecated function t3lib_stdGraphic->imagecreate()

[Stefan Galinski]

This is an SVN patch request.

Type: Code Cleanup

Bugtracker references:
http://bugs.typo3.org/view.php?id=14813

Branches:
TYPO3_4-4, trunk

Problem:
The function t3lib_stdGraphics->imagecreate was deprecated in TYPO3 4.4. 
Unfortunatly there are still some occurences in the core.

Solution:
Replace the existing occurences with imagecreatetruecolor like it's 
suggested by the deprecated function itself. IMHO this is a no-brainer...

Note:
There are some further deprecated method calls to t3lib_stdGraphics-
>reduceColors if you don't enable png_truecolor. Unfortunatly I didn't found 
a reliable way to remove them without breaking backwards compatibility. 
Maybe someone else with more knowledge about this stuff, can fix them later 
on.
