* Add constraint_bounds function to Quad implementation
* Respect Clip property when exporting All Artworks and centering document using the ctrl + 0 hotkey.
Calculate artboard_clip_bounds and then constraint the all_layer_bounds to respect the bounds of the Clipped Artboards.
* Use parent_artboard to find ancestor artboards of each layer and constrain bounds if artboard is clipped
* Remove redundant comments
