UltimateZoneBuilder/Source/Plugins/BuilderModes/ClassicModes/DrawGridMode.cs
MaxED 712dbd03e8 Cosmetic: renamed Drawing mode to Draw Lines mode.
Changed: current 2D position and zoom is now stored in the .dbs file when saving the map and restored when opening it (should this be turned into toggleable option?).
Draw Lines mode, Draw Curve mode: you can now hold Alt - Shift to snap to 8 cardinal directions.
Draw Rectangle mode, Draw Grid mode: you can now hold Alt - Shift to draw square shapes.
Draw Ellipse mode: you can now hold Alt - Shift to draw circle shapes.
You can now hold Alt - Shift to snap to 8 cardinal directions while dragging map objects.
Fixed, Draw Lines mode: line angle is now displayed in 0..359 range (was -45..314).
Fixed, Linedef info panel: line angle is now displayed in 0..359 range (was -45..314).
