Visual Mode: fixed an issue where trying to apply a rotation to things that were not seen yet would cause a crash

Fixed a problem where not selected geometry and things could not be dragged when the "don't move selection if any part of it is outside of map boundary" option was enabled

Visual Mode: fixed a problem where the selection order was not kept when synchronized selection between visual and classic modes was enabled. Fixes #938

Visual Mode: fixed a problem where things directly touching the top of 3D floors were rendered with the incorrect brightness. Fixes #940

Visual Mode: changes to Eternity Engine's upper/lower texture skewing definitions are now shown in Visual Mode

Visual Mode: fixed a crash when toggling visual vertex slope picking and the map contains double-sided linedefs without a front sidedef. Fixes #928

- fixed a rare condition where skewed mid textures were not clipped correctly
- fixed a problem where translucent mid textures were not skewed correctly
- fixed a problem where sprites were skewed unintentionally

Draw Grid Mode: fixed a problem where "continuous drawing" would redraw all previously drawn shapes each time a drawing was finished. Fixes #912

Added action to change the index of linedefs, things, sectors, and vertices. Can be accessed through a shortcut (not bound by default) or the menu of the respective mode (#903)

Edit Selection Mode: fixed a problem where floor and ceiling textures were unintentionally scaled in UDMF when resizing the selection. Fixes #873

Map Analysis Mode: fixed a problem where lines with fractional vertex positions could erroneously be reported as overlapping

Disabled visual sloping for game configurations that do not support plane equation slopes. Fixes #828
Added toasts for visual sloping events

Behavior can be configured in the "Toasts" tab in the preferences.

Tag Range plugin: fixed a problem where the new tags were not displayed in Sectors Mode when selection numbering was disabled. Fixes #795

Sectors Mode: fixed a regression where sector labels were not updated after editing sectors. Fixes #793

Fixed a regression where editing map elements did not preserve the selection order, but used the index order instead. Fixes #791

- editing a highlighted, not selected map element will deselect other selected map elements, then start editing the highlighted map element
- dragging a highlighted, not selected map element will deselect other selected map elements, then start dragging the highlighted map element
- dragging a single map element will keep its selection state. I.e. dragging a selected map element will not deselect it after dragging anymore
  - dragging a highlighted, not selected thing will not select it after dragging
- dragging a highlighted, not selected sector, while other sectors are selected, will only drag the highlighted sector, and not the selected sector (and deselect the selected sectors)

Linedefs Mode: fixed a problem where the "Select Single-sided only" and "Select Double-sided only" actions would still display the selection numbers of deselected linedefs

Visual Mode: fixed an issue where using the "apply camera rotation to things" action did not update the thing cages properly

Draw Settings docker: fixed an issue where toggling the texture check boxes stopped texture overrides from being applied

Map element associations: fixed a problem where things that have a argument of type tag set to 0 were referencing all things with tag 0. Fixes #718

Linedefs Mode: fixed a crash that could happen when the mouse was moved out of the map control while an UDBScript was modifying the map

Sectors Mode: fixed a crash that could happen when the mouse was moved out of the map control while an UDBScript was modifying the map

Edit Selection Mode: improved handling of texture transformation (still doesn't work 100% correctly)

Map Analysis Mode: fixed an issue where lines were erroneously reported as overlapping in certain situations. Fixes #713

Visual Mode: Fixed a problem where using visual sloping a slope handle around itself resulted in invalid slopes
