// History:
// Ken Bertelson - 12 Apr 2000 - Split CGridCell into CGridCell and CGridCellBase
// C Maunder - 19 May 2000 - Fixed sort arrow drawing (Ivan Ilinov)
// C Maunder - 29 Aug 2000 - operator= checks for NULL font before setting (Martin Richter)
// C Maunder - 15 Oct 2000 - GetTextExtent fixed (Martin Richter)
// C Maunder - 1 Jan 2001 - Added ValidateEdit
//
// NOTES: Each grid cell should take care of it's own drawing, though the Draw()
// method takes an "erase background" paramter that is called if the grid
// decides to draw the entire grid background in on hit. Certain ambient
// properties such as the default font to use, and hints on how to draw
// fixed cells should be fetched from the parent grid. The grid trusts the
// cells will behave in a certain way, and the cells trust the grid will
// supply accurate information.
