[TYPO3-core] RFC #16375: Add a new TypoScript option "resolution" to the image resource

[Stefan Geith]

This is an SVN patch request.

Type: New feature

Bugtracker references:
http://bugs.typo3.org/view.php?id=16375

Branches:
Trunk

Problem:
Sometimes a higher resolution as the display-resolution of an Image (TS 
IMAGE-Object) is needed.
E.g. if you want to render PDFs from your HTML-Output, you coulld need 
higher resolutions for images, if you want to print them.
This is not possible in the moment.

Solution:
New option for the imgResource that would be helpful:
resolution = 300 -> creates an image, that has 300 DPI

Note:
Until now, it is impossible to render images with another width/height 
than given in the img-parameter. You can't render an image to e.g. 
640x480px and then create an img-tab with widht="320" height="240".


Thanks to Benjamin Mack for taking care of this one!
