Tick List Management

A label block can maintain a CPtrList of CPoint objects, one for each label. These CPoints are updated every time a new set of label positions is calculated. The point list is used to place grid lines or tick marks next to labels.

To activate tick list management, call SRGraphLabelBlock::SetLogTickPositions(TRUE).

To supply your own tick list for updating, call SRGraphLabelBlock::SetptrTickPositionList().
