  • Left/Top values of all objects (including groups) correspond to an object's center, and are relative to top/left corner of a canvas. Left/Top values of objects in groups are relative to groups' centers.

  • SVG parsing doesn't work with node 0.6.8. This is due to one of fabric dependencies — o3-xml.

  • new fabric.Canvas('foo') wraps <canvas id="foo"> element with a <div> one, and adds another (absolutely positioned) canvas element on top of existing canvas (the one with id="foo"). This only happens for dynamic canvases, not static ones (fabric.StaticCanvas).
