🎉 Add new shape & rect data structures

Browse source 
Also optimizes some functions for faster shape and rect props
access (there is still a lot of work ahead optimizing the rest of
the functions)

Also normalizes shape creation and validation for ensuring
correct setup of all the mandatory properties.
