When dragging in a vertical or horizontal region,
there is no need to detect the drag axis.
Gives minor usability improvement for dragging over vertical tabs.
The intention is to fix a too low default threshold on high DPI screen.
Users with high DPI screens that have increased the threshold to fix this
or liked the lower threshold will need to lower it again.
This is still somewhat of a guess, ideally this would be based on the
physical distance travalled, and maybe different per type of input device.
However we do not have access to this information, and hope this gives a
better default.
Complex rigs are built from many bones (often overlapping)
connected by constraints.
When investigating or debugging such rigs one often wants to switch to
the target of a constraint, or a parent bone, but it is difficult to do
manually due to overlap confusion.
This adds a right click menu option that automatically selects
and makes the target object or bone active for UI fields where a
suitable reference is readily available.
Previously copy and paste was handled within the same function using a mode switch, which is quite ugly in most cases.
This patch separates the function into two and splits up those in even smaller functions to increase maintainability.
Finally one new feature was added: You can copy from disabled fields now. (requested by hjalti)

Displaying the labels tip immediately feels too intrusive,
make this work more like regular tooltips, displaying more quickly.
Tooltips can now uses multiple passes, each pass with it's own delay
for the next pass to show.
This reverts commit 357b72e0a7 which caused
the issue, we need a better fix for that cosmetic issue from T50862. For
now displaying keyframes and drivers is the more important one.
block and layout could be NULL and checking this everywhere
wasn't practical.
Instead of lazy initializing, add UI_popup_menu_end_or_cancel
which cancels empty popup menus.
