- fix : removed duplicated code between ImageResizer and CanvasUtils (disabledImageSmoothing utility method) - added pskl.utils.UserAgent, basic user agent sniffer. I need it to sniff out IE10 for frame rendering (and it's not possible to feature detect here). Can check isChrome, isFirefox, isIE and get the version for each of them - added resizeNearestNeighbour in ImageResizer. Readapted from piskel website, this allows us to 1 - resize without AA on IE10, and 2 - add a pixel gap to reenable the GRID - finally : added back support for GRID ! - also extracted the 'zoomed out background color' as a constant in Constant.js
