//CurrentPoint reports the current point of the current path.

//The current point is returned in the user-space coordinate system.
//
//If there is no defined current point, or if c is in an error state,
//(ZP, false) will be returned.
//Otherwise the (cp, true) will be returned where cp is the current point.

//Most path constructions alter the current point.
//
//Some functions use and alter the current point, but do not otherwise change
//the current path, see ShowText.
//
//Some functions unset the current path, and, as a result, the current point,
//such as Fill.
