pAdx (PLONG) - input
Pointer to an array of LONG integers, one element for each character in the string. When CHS_VECTOR is set, this array is used to set the spacing between characters. Each element is the distance in world coordinates from the bottom-left corner of the corresponding character in the string to the bottom-left corner of the next. The distance is measured along the baseline for left-to-right and right-to-left character directions, and along the shear line for top-to-bottom and bottom-to-top character directions. The final element is used to reposition the current position, when necessary.
