This fixes drawing on a surface that has different settings (like
scaling) than the display surface, by performing the measurements on a
layout properly set up for the target surface.
In practice, this fixes e.g. printing on a scaled surface.

"default" was mapped to "value" which is normally a string-like
style rather than a "default" type of style which make some themes
that set different background colour for strings to look weird for
config files highlighting.
When performing a regular expression search on a range, and there is a
match past the end of the range, search_find_text() used to improperly
return the position of the match, but without filling the
Sci_TextToFind structure. This lead to the calling code assume there
was a match, and maybe read the uninitialized fields in the
Sci_TextToFind structure, thus leading to undefined behavior.
So, fix search_find_text() so it properly returns -1 when there is a
match but it is outside the bounds.
When pasting with the X primary clipboard (middle mouse button), the
user expects the focus to be grabbed by the widget receiving the data.
No idea why the VTE itself don't grab upon middle click, though.
Getting the statusbar context ID using the context registration API
allows for other (namely, plugins) to register their own context
without a risk of overriding Geany's one.
Although using menu items for these is not very practical, it helps
discoverability, and they're more useful and intuitive than 'Transpose
Current Line'.
This copies the current document text and properties into a new
document, similar to the old Save As 'Open file in a new tab'
option, but easier to understand and decoupled from saving.
One notable difference is that the new document does not copy the
filename - the old behaviour was confusing and error-prone for the
user (e.g. editing two documents with the same filename).
