Make changing objects possible

[jtl5770]

Is your feature request related to a problem? Please describe.

The "problem" - if you can call it like that - is that currently it seems to be not possible to change a shape/object after it has been created. There is actually no notion of a collection of objects/shapes that can be changed at all, just the possibility to once add to the canvas like in a pixel drawing application. I would like to have it behave more like a vector drawing editor that knows about all the objects on the canvas and can change them at any time.

Describe the solution you'd like

• Know about the list of objects that have been created with all their parameters including z-Index and do the display on demand from this list, making sure that hidden features are not drawn. This also includes having the typical operations of bring to front/bring to back/lower/raise and the ability to select an object for changing at all.
• Have a native file format that saves this information so it is still there after save/load.
• ...I assume there is more to enabling such a feature set than these points mentioned.

Describe alternatives you've considered

• using a real vector graphics editor or diagram editor, but the selling point for ascii draw is that is exactly not such a complex beast.

Hello, this is definitely a very interesting idea, but I would need to change a lot of the code to add this.
