On non-Windows, the icons are installed on the system's icon directory,
so installing our index.theme might override the system's one. Since
it's highly unlikely the theme index is missing on non-Windows, just
don't install it.
Install all icons on Windows, as well as a theme index because the
system doesn't have one and one is required.
Also install the theme index on non-Windows, although it shouldn't
be necessary because the system is likely to provide one.
A preference for an icon doesn't make sense; if someone don't like
her theme's icon she should either switch to another theme, override
that specific icon or don't bother.
This reverts commit 6897cd49c69535c6563e56ae011c6f8382fec485.
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.
(Applied to Scintilla HG as 74c71632dd1afa726b0f1608d13413e0864da9b0)
"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.
