NOTE: This revision breaks existing code if the worksheet's DefaultRowHeight/DefaultColWidth is changed - value must be in millimeters now. Methods for accessing individual row heiths and column widths are fine, but are marked as deprecated, they use the old units. Optionally a unit parameter can be specified. git-svn-id: https://svn.code.sf.net/p/lazarus-ccr/svn@4568 8e941d3f-bd1b-0410-a28a-d453659cc2b4
