Generally, this is a very valid concern. In some places where we found 
out (or just assumed) that it makes a difference, we currently use 
smaller integer types directly for member variables, instead of enum. 
For example, see eCellType in ScBaseCell (sc/inc/cell.hxx). Or 
FormulaToken (formula/inc/formula/token.hxx), where the type of eOp and 
eType even depends on DBG_UTIL.

I don't know if Font objects are constructed in very large numbers.
