Before this fix, a multi-layer mask movement/scaling (with mixed layer
types: normal layer and tilemap layers with different grids) caused
loss of drawing areas.
The heart of this solution is to correctly align the 'selection mask'
and 'transform data' according to the layer's grid, and also, forcing
'site' TilemapMode/TilesetMode before each
reproduceAllTransformationsWithInnerCmds() iteration.
During the life of a PixelMovement object there is a tilemap mode lock.
Additionally arrow keys now work to move a selected area in
TilemapMode::Tiles.
This fixes several problems in MovingPixelsState where hidden layers
were transformed anyway when we switched the visibility of a layer in
this state.
Other fix was tried before in #3254 but we needed the onBefore/After
layer visibility change notifications to make this work properly
(i.e. drop pixels when the visiblity of a layer is changed).
The only drawback at this moment is that changing the visibility of
the non-active layer when we are transforming multiple cels/timeline
range can be confused because we don't have #2144/#2865 implemented
yet.

* Remove "%3d" for integers (just use "%d"), this is a legacy format
when the text was a monospace font (it was present from the very
beginning of the times, when we used the Allegro font)
* New :delta: icon (before :offset: which didn't exist in the theme)
* Show useful info for MovingCelState: mainly cel bounds
Mainly for Line-like tools (which require the last mouse position
only). Related to #3119, possible fix for several performance issues
on Linux mainly.
When we clicked the current cel/frame/layer on MovingPixelsState in
the Timeline, we weren't dropping the pixels, so the range was
different in the Timeline UI, but we were using the old site range
which was different (bigger) than the Timeline range.
Fixes several bugs: https://community.aseprite.org/t/8618
* Moved all clipboard:: functions inside app::Clipboard class
* Convert app:📋:ClipboardFormat enum to
app::ClipboardFormat enum class
* Added app::Context::clipboard()
This is the first version of the feature, it still needs some
fixes (e.g. avoid skew transform when the pivot is in the same side of
the skew handle which can calculate a division by zero).
This should be enough to fix a crash reported where we receive a
onUpdateStatusBar() when m_pixelsMovement is already deleted. It's
called from onLeaveState() when we call notifyGeneralUpdate() which
generates a scroll change and finally updates the status bar.
