I can agree that not all different kind of shapes fits all kind of
purposes, but I still think that we would benefit from having both a
common code and a common atlas representation of shapes.
While the code can be common for parsing the shapes, different kind of
properties might have different kinds of shapes available. The changes
made to Mercator with the addition of atlas parsing of shapes was made
with such a harmonization in mind.
If the way shapes are defined for the terrain mods, there's a "shape"
attribute which in turn has a "type" attribute describing the type of
shape, and then different other attributes defining the shape, dependent
on the type.
For spawn areas I would actually think that circles and rectangles would
be more suited than polygons, since the math for generating an evenly
spread random point within the shape probably would be simpler.
I did the code for the terrain mods; if you want I can take a stab at
implementing this for the spawn points too.
Another question regarding the spawn points: I see that there is proof
of concept code in SpawnEntity::populateEntity
Is the idea to let this be data driven, or to let it be implemented in a
