\since 6.4
\brief Defines a pill-like shape.
This type defines a capsule shape. This is a cylinder with a hemisphere at each end.
The origin is at the center of the capsule. The capsule is specified by \l diameter, which
determines the diameter of the cylinder and the hemispheres; and \l height, which
determines the height of the cylinder.
\note When using scaling transformations with this shape, the x component will be used to scale the height and
the y component will be used to scale the diameter. The cylinder will always be perfectly circular even if the
scaling transformation is non-uniform.
