Ability to resize images in Fototoon

[hharshas]

Earlier, the image was displayed via "backgroundImage", so its only way to resize it was to resize '#mainCanvas' div ~ entire page, that will be no good. I tried to use existing Globe 'TYPE_Rectangle' by adding bitmap (easel js) to it, but many other component are "TYPE_RECTANGLE" and it is hassle to make each component behave same after these changes (This is my final result but bitmap fills image in parent element). Final solution that i can understand is creating a unique Globe type "TYPE_IMAGE" and working with it, that may takes time. If someone is willing to help me with this then i will continue. https://github.com/llaske/sugarizer/issues/1551
