Note that the same issue actually showed without a frame node, when
trying to click-drag on a socket on its 'inside node' part, you would get
same behavior.
Only solution I can see here is to prevent Node selection to go on when
user clicks on one of its sockets, there is no way afaik to make
drag-from-socket to start if we keep select-node operator running
modal, since both operators (NODE_OT_select and NODE_OT_link) use the
same shortcut, if select (which is checked first, being a Tool) returns
modal, then event is considered handled it seems, even though
Passthrough is also returned...
Left-click select broke that behavior, since it puts both action and
select buttons on the same physical mouse button...
To support this behavior again, we have to split selection process in
two steps, hence make it modal... While I remain rather skeptical about
that global design decision, and complexity it adds to many UI/UX areas,
this solution ends up being OK-ish I think.
Thanks to @brecht for some final tweaks on the patch.
Refactor a bit node selection code, mostly in the socket selection in
one place 'extend' logic usage was inverted, deselection of other
sockets/nodes was not working properly.
Also now make node active when selecting a socket, this makes more sense
and makes the NODE_OT_link_viewer macro much more useful (this is the
only user of the 'socket select' feature currently, afaics).
Request from the Spring team. When compositing the CTRL-Shift Click on a
node cycles the viewnode with an output socket. When you have many
render layers you spend time cycling to the desired socket. This patch
allows the user to CTRL-Shift Click on a socket to connect directly to
that socket.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

Was using UI_BLOCK_LOOP to control draw style,
this meant we couldn't use popup theme colors for cases
where it the interface has the same purpose as a popup but happens
not to use this flag.
Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.
Previously, hitting Shift-LMB will first invoke selection operator, which
then later on is transformed to mouse tweak used for reroute operator.
This was causing problems extending selection with Shift-LMB when clicking
fast or from a tablet.
Border and circle select wait for input by default.
This commit uses bool properties on the operators instead of
magic number (called "gesture_mode").
Keymaps that define 'deselect' for border/circle select
begin immediately, exiting when on button release.
Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
