Multiple anchors for room resizing

[ElectroDev1]

Is your feature request related to a problem?

Currently, rooms can only be resized from a top-left anchor, meaning that increasing its size will only add space on the right and bottom sides. This becomes frustrating when making, for example, very vertical levels, as all you can do to add space upwards is increase the room height and move every single asset in the room downwards. Currently the room editor only helps for specific types of games in this regard, which is really not a great thing.

Describe the solution you'd like

The current way to resize rooms (the two input fields in the inspector), would have an additional anchor menu that would look similar to ones found in many painting programs.

Here is a mockup example, with the existing fields more separated to the Persistent and Clear Display Buffer buttons

"Anchor" could also be renamed to "Origin point" or "Reference point".

This anchor point would of course only affect room editing, no in-game room resizing.

Describe alternatives you've considered

An alternative solution could be to allow for the room to be resized in a more visual way by dragging points at the edges and vertices of the room to change the room's size (again, similarly to many painting programs). Holding shift would of course allow you to maintain the same proportions of the room while resizing.

Highly needed addition!

Why do we still have a room size? It should just be an infinite canvas starting from the point 0,0
It would make it much more in-line with other engines and cause less confusion in terms of screen size/window size/room size

I really need it

Absolutely crazy that we don't have this yet

I've wanted this since forever. Being able to resize a room from various anchor point, just like when editing a sprite, would be game-changing (pun unintended)

To those whom it may concern, I made a third-party tool to help with this:

It's not perfect, but it should handle the general "add pixels to left/top" cases.
