Regarding $incircle, you can use this in the meantime:
Code:
alias inellipse {
  if $calc((1 - (2 * ($1 - $3 - $5 / 2) / $5) ^ 2) ^ 0.5 * $6 / 2) && $&
    $abs($calc($2 - $4 - $6 / 2)) isnum 0- $+ $v1 { return $true }
  return $false
}


Syntax is $inellipse(X,Y,x,y,w,h)
Checks whether point X,Y is inside the ellipse (or circle) x,y,w,h. For a more legible and flexible (and less optimized) version of the above, as well as info on how it works and examples, check this out.
