Zoom independent point object size

[natebot13]

Is your feature request related to a problem? Please describe.
Point objects are quite large for low res tile maps. I'm working with an 8x8 tilemap, and the point object covers nearly 6 tiles.

Describe the solution you'd like
It would be nice if the point object scaled with the zoom so it stays a consistent size no matter the zoom, much like google maps pins. This way, in order to access an object under the point, I can simply zoom in and it will "shrink" out of the way. This solution does mean that point objects will look a lot bigger when you zoom out, so either a maximum size or some nonlinear scaling could be applied such that points don't cover maps when zoomed way out.

Describe alternatives you've considered
An alternative could be to have the point object have a configurable size in the settings, or perhaps just a size relative to the current map's tilesize.

First of all I've taken the simplest route, which is just to ignore viewport transformations for these objects. That will indeed make them stick out a lot when zooming out far. Please let me know whether that's a problem or not. Builds with this change can soon be found at https://github.com/mapeditor/tiled/actions/runs/2421132404.

This change made them usable for my needs. In this build I did get a drawing bug after placing a point, see screens with before placing point and after, notice the black duplication and weird lines.

Ah, thanks for catching that! Should be easy to fix.
