[TYPO3-core] RFC Feature #9292: Integrate hook at the end of tslib_cObj::getImgResource

[Oliver Hader]

This is an SVN patch request.

Type: Feature

Bugtracker references:
http://bugs.typo3.org/view.php?id=9292

Branches: Trunk

Problem:
Imagine you'd like to post-process any image file by a special effect
that is not covered by the current standard possibilities of ImageMagick
or the image rendering functionality of TYPO3 in general.

Solution:
Add a new hook to the bottom of the getImgResource() method. Since the
regular image rendering would just return the result this is now put to
the local variable $imageResource and processed by the hook later on.

Notes:
You can use the attached unit test to ensure that the hook object gets
called correctly with the expected information.
