Updates a collapsible node's bounds in case the text at the collapsible node is being deleted partially.
This function is called by the edit control to properly update a collapsible node's bounds in case the text at the collapsible node is being deleted partially. Unlike CBCGPOutlineBaseNode::UpdateBlocksForDeletedRange, this function updates all its sub-nodes as well.
| nStart | Specifies the start zero-based offset in internal buffer of the edit control | 
| nEnd | Specifies the end zero-based offset in internal buffer of the edit control. | 
Reimplemented from CBCGPOutlineBaseNode.
