1999-05-22 Michael Natterer <mitschel@cs.tu-berlin.de> * app/[all files with resolution info] * libgimp/gimp.h * libgimp/gimpimage.c * libgimp/gimpsizeentry.[ch] * libgimp/gimpunit.[ch] * plug-ins/newsprint/newsprint.c * plug-ins/pgn/png.c * plug-ins/tiff/tiff.c: double instead of float for all resolution and unit-factor variables. * app/commands.c * app/crop.c * app/interface.c * app/layers_dialog.c * app/move_tool.c * app/resize.c * app/rotate_tool.c * app/scale_tool.c: pass the image's unit *and* gdisp->dot_for_dot to all functions which create sizeentries. Never create a sizeentry with UNIT_PIXEL but with the image's unit and set it's unit to UNIT_PIXEL after creation if dot_for_dot is on. This way the image's unit can always be picked from the menu without selecting "More...". * app/interface.c: made the query_*_box() functions use the ActionArea. * plug-ins/gimpunitmenu.c: GTK_WIN_POS_MOUSE for the unit selection dialog.
