// Usage: As Module

// Arguments:
// r = radius of spherical portion of the bottom. Default: 1
// ang = Angle of cone on top from vertical. Default: 45 degrees
// cap_h = If given, height above sphere center to truncate teardrop shape. Default: `undef` (no truncation)
// ---
// circum = set to true to circumscribe the specified radius/diameter. Default: False
// realign = adjust point alignment to determine if bottom is flat or pointy. Default: False
// d = diameter of spherical portion of bottom.
// anchor = Translate so anchor point is at origin (0,0,0). See [anchor](attachments.scad#subsection-anchor). Default: `CENTER`
// spin = Rotate this many degrees around the Z axis after anchor. See [spin](attachments.scad#subsection-spin). Default: `0`
