[TYPO3-core] RFC #11177: Feature: New options noRescale and resolutionFactor for getImgResource()

Hi,

> resolutionFactor=N -> creates an image, that has N times higher 
> resoultion than displayed

sorry, I like the general idea, but I don't like the way it's done. The 
"resolutionFactor" is somewhat odd to me. For me it would make much more 
sense to actually define the dpi (Dots Per Inch), so that based on the 
given width and height and the dpi you can calculate the total 
dimensions (default for screen are 72dpi). Would make much more sense to 
me and could actually be used for print images. By setting this option 
the internal dpi value of the image should also get changed (shouldn't 
be a problem with imageMagick I guess).

I'm also not sure if it would make sense to implement another option 
like displayWidth and displayHeight, that would override the img-tag 
properties. This would allow same functionality like your "noRescale" 
option, but also allow resized images to be displayed in different 
dimensions. But I haven't thought about that very well.
