There were two issues here actually:
* The hack to allow running Blender directly from the source directory
would just check for a 'release' directory, without actually ensuring it
is release dir from blender source tree, and not some other random
folder.
* GHOST_getSystemDir returns nothing for portable installations, now
we'll then check directly in the blender binary dir in that case.
This fix is more critical in 2.8 branch, where that system path is used
to retrieve new '3D' icons...
* Draw the frame/time number box over the scrollbar instead of above it,
to reduce the clutter/clashes with markers.
* Draw the box centered around the line instead of off to one side,
making it clearer that the frame shown is the one being affected.
* Make the box larger than the scrollbar + use white text to make it
stand out from the neighbouring frame numbers (otherwise, it's easy
to misread that it's just another one of those)
Based on discussions here in the office, this commit introduces a number of
changes to make the "Bind Camera to Markers" feature (introduced during Sintel
to facilitate camera switching, and now an integral part of the UI for doing this)
nicer to use.
Main changes:
* "Camera Markers" are now drawn using Camera icons, making it easier to
distinguish between them and other ("normal") markers
* "Camera Markers" will display the name of the bound marker, making it
easier to see what camera each marker uses. This will then also stay
in sync with the camera being used (though a manual refresh is needed
after renaming objects to make the timeline update), fixing the problem
where the marker's camera and the name get out of sync.
* Behaviour of Ctrl-B has been modified to make it easier to quickly add
these markers. Now, it will directly add a new marker on the current frame,
bound to the currently selected camera object. If there's an existing marker
on that frame, the existing marker's camera will be replaced instead of making
a new marker.
With the clear separation between data and a state we need to make sure
operators and other areas are readingstate from evaluated datablocks.
Code-wise it means that all evaluated values are to be read from dataglock
which is owned by dependency graph, using DEG_get_evaluated_id() or similar
helper.

Each parameter of the function is copied into the memory stack.
This also brought an improvement in peformance of snapping functions between 5% and 12% in my tests.
