Rounded rectangle

[dennisorlando]

• created a RoundedRectangle struct, pretty much copy-pasted from Rectangle
  • it doesn't have an "intersect" function
  • it doesn't implement PrimitiveZero
  • it has some additional functions like "as_rectangle" or "from_rectangle" or "radius()"
• added some quality-of-life getters to Rectangle and RoundedRectangle
  • top(), left(), right(), bottom(),
• created a draw_rounded_rectangle() function for Graphics2D which uses an 8-vertex polygon and 4 arcs

I don't think I know how to complete the various missing "draw_rounded_*" functions: it would be lovely if someone else knows how to write them :3 (perhaps a new "rounded_rectangle" branch?)

We should keep the behaviour consistent (this should also be exclusive)

I wasn't sure about how to handle the curves: there isn't a real "bottom" if the corner is a curve. By "exclusive" do you mean that instead of always inclusive it should be always exclusive? In which case it would be different from the Rectangle's contains() anyways

Perfect, thanks again for this! If you have any questions please let me know.

Hey @dennisorlando, thanks for making the changes! Just checking if this is ready for re-review? It looks like there's a merge conflict in web.rs.

Hey :) I think so (?) there's the exclusivity / inclusivity problem of the "contains" method that is left unsolved; I left it as it is, therefore always inclusive

(I made some mess with branches and merges because of inexperience, I made a new branch and created a new pull request)
