Enable drag image around canvas #10
Description
When an image bigger than 512 x 256 (the Hack screen size) is loaded, the image is trimmed to these dimensions and it snaps to reference position p(0, 0). This feature aims to enable the user to drag the image around the canvas in such a way that he/she can position the image at will before generating the assembly code.
- update cursor icon when the image can be dragged
- maybe show offset information
