>> 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 options for the imgResource that would be helpful:
>> noRescale=1 -> creates image, as ususal, but doesn't resize original file
>> resolutionFactor=N -> creates an image, that has N times higher 
>> resoultion than displayed
>>
>> Example:
>> Imagine an uploaded Image of size 1500x1000 pixel.
>> If you create an IMAGE-Tag by TS with width=320m, then the Image will 
>> be rendered to 480x320 pixels and the width/height-params of the 
>> created <img>-tag will be also 480x320.
>> If you want to zoom-in on the website or you want to create a PDF from 
>> the page, then the resolution is to low.
>> With use of noResize=1 an IMAGE-Tag will be rendered with 
>> width/height-params 480x320, but the src-param will be the _original_ 
>> image (having 1500x1000 pixels).
>> With use of e.g. resolutionFactor=2 an IMAGE-Tag will be rendered with 
>> the Image scaled to 960x640 pixels and the width/height-params of the 
>> created <img>-tag set to 480x320.
