Add support for HDPI screens (retina)
Adding support for the HDPI screens that are coming (and also here already) would be a good thing for redmine (at least in the interface).
Currently the app looks good generally, but some parts like the icones are fuzzy and become distractive on HDPI screens.
There is a choice concerning the method of implementation:
- Make all graphics hdpi and force their size of each image on the page.
- Use the JQuery plugin http://troymcilvena.com/post/998277515/jquery-retina
- Use a custom solution...

The best way seems to be : send everything in x2 versions to everybody.
So I started tinkering with the code. Currently when I call image_tag there is no way to get the real size of the image without reading each image. Is there a way to store these values in a cache after the first read?
I intend to also collect data about image versions (cancel.png, cancel-1.5x.png, cancel-2x.png ...). Should I store that in a cache to avoid nailing the disk on every request?
I might create a second function hdpi_image_tag to allow enabling/disabling the option and leave image_tag to its current purpose.
Would this be the right approach?
