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

{ This demo is a test for recursive calculation of cells. The cell formulas
|
|
are constructed such that the first cell depends on the second, and the second
|
|
cell depends on the third one. Only the third cell contains a number.
|
|
Therefore calculation has to be done recursively until the independent third
|
|
cell is found. }
