2002-12-17 Michael Natterer <mitch@gimp.org> * app/tools/gimptransformtool.c * app/tools/transform_options.[ch]: replaced the totally unclear (to the user) way we used to calculate the number of grid lines from the value entered in the "Density" spinbutton by a system where the user has the choice between the number of grid lines to display and the spacing between the displayed grid lines. Replaced the "Show Grid" toggle by an option menu to choose the grid type from. (idea from drc on #gimp).
