Whether or not to output high-resolution images for high-DPI displays.
This is primarily targeted at tablet browsers and newer desktops and laptops, such as the MacBook Pro with Retina display. On these high-DPI devices, raster images appear blurry or pixelated by default without special treatment.
When generating thumbnail images, thumbnails are rendered not only at the requested size, but at 1.5x and 2x the requested size.
srcset attribute is included on the
img specifying these larger images for the appropriate display densities.
window.devicePixelRatio for most browsers, and a compatibility fallback for IE 10, and applies srcset -> src change automatically.
On browsers with native
srcset support, this disables itself automatically.
Currently (as of 1.21) this code applies only to images created through Linker methods; image galleries and file: page detail displays are not currently affected. This should be changed at some point by migrating support lower down in the MediaHandler arena.
Currently (as of 1.21) the densities used (1.5x and 2x) are hardcoded and not configurable. 1x is the implied default density of the main image.
