GPencil: Fix memory leak issue

After a previous commit to use unique identifiers for Ghash key, I had missed to free the memory of the name key.

Thanks to Jacques Lucke for detecting the leak.

Keymap: use tap/drag for mode switching w/ pref enabled

Cleanup: remove redundant property assignment

Also cleanup comments

Depsgraph: Make it easier to control which bases being pulled into the graph

Just de-duplicates some logic. Should be no functional changes.

Move base flags evaluation to its own function

No need to have iterator loop in the view layer evaluation,
this only makes it more difficult to have base flags covered
by the dependency graph.

Other good thing is that we don't need to worry about whether
base has been removed from the evaluated view layer or not.

Transform: shear redo support for other orientations

Shear gizmo now uses a single orientation and sets
different ortho axis instead of constructing a different matrix for
each handle - allowing the redo panel to select orientations.

Fix T61988: Bevel mitering on small objects.

When edges had small length (less than about .005) the angle
classification didn't work. Needed some normalization of vectors.

Fix typos related to units

Cleanup: use "_pad" prefix for pad vars

Cleanup: header guard names

Missed in file rename.

Fix T61945: Scaling with invalid snap distances

ApplySnapResize did not take into account invalid distances. Added check for this.

GP: Use unique names for instance objects

When instance objects linked, the name could not be unique.

GP: Check if Instance loop is needed

This reduces the loop time if the scene is not using instances.

GP: Optimize Instances drawing loop

Transform: refactor orientation naming and usasge

Transform orientation was previously related to constraints,
recent changes meant it was used even when not constraining to an axis.

Now transform orientation is separate from axis constraints.

Correct error in recent transform refactor

DRW: disable wide edges when face-dots are used

Users who prefer to use face dot's don't get an advantage from drawing
thicker wire.

Cleanup: remove runtime structs from DNA
