boost/signals2.hpp is a convenience header, it seems that
boost/signals2/signal.hpp is enough for our needs.
This allows to get rid of 6MiB of header files in 3rdparty/boost (and
probably to speed-up compilation).
1/ remove boost regex code from 3rdparty/boost. Only the cmake stuff remains.
2/ remove traces of BOOST_LIB since there is no need anymore to
compile boost stuff.
3/ remove traces of boost regexp in config/lyxinclude.m4 and INSTALL
4/ require gcc 4.9 as minimal version in autoconf.
Unfortunately, the net gain is only 10% of included boost size (now 21M).
This restores the debug output as it was intended before the
introduction of the LYXERR macro that was unconditionally outputing
an end of line. This is how this output was appearing until lyx 1.5:
Looking for font family cmr10 ... got: cmr10
got it normal!
instead of as it was since lyx 1.6 and until now:
Looking for font family cmr10 ...
got: cmr10
got it
normal!
Using US english desktop language LyX's Mac OS adds some items to the view menu:
1. Show/Hide Tab Bar and
2. Enter Full Screen
These items won't work properly and it's better to hide them.
Mac OS adds two extra menu entries to the edit menu.
These menu items are:
1. Start Dictation...
2. Emoji & Symbols
Both menu items don't work with LyX.
Therefore they shouldn't be present and the new code hides them.
This patch aims at:
1. replacing absolute paths by their hashes (do not leak directory structures)
2. not using counters anymore so that changing figures order in the document
does not lead to large number of obsolete images in export directory.
Other changes than in xHTML export of images are unintended.
The is a fixup to commit 611df441. It seems that the wrong unicode
property was selected. It could be that both classes should be used.
Fixes bug #11900.
