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).
Includes a fix when wrappers are used with empty paragraphs. The logic is probably wrong if two legit wrapped paragraphs have one empty paragraph in the middle. This is only for slightly convoluted cases... Wrapping decisions should rather be taken for a series of paragraphs at once, but it would be more complex to implement and would only solve very peculiar cases like these ones.
CaretGeometry is defined as a struct, but was forward-declared as a
class. Now we forward-declare as a struct. This addresses the
following Clang warning (that does not appear with GCC):
src/frontends/CaretGeometry.h:27:1: warning: 'CaretGeometry' defined
as a struct here but previously declared as a class; this is valid,
but may result in linker errors under the Microsoft C++ ABI
[-Wmismatched-tags]
The current code did not give much information.
I am not sure why the <<FontInfo operator is not defined in
FontInfo.h, but I figured that it was not necessary to understand that
now.
The exception is raised when an included file fails to export
because e.g. it is from a newer version of LyX or because an
intermediate command such as knitr fails.
The exception was introduced at 1a374a93 so that the export of a
document exits with error if an included document exports with
error.
This commit catches the exception when the LaTeX is asked for in
order to generate a preview of the included file.
The caret geometry is now computed in BufferView as a list of shapes
(caret, horizontal l-shape if needed, completion triangle if needed)
kept in a variable of type CaretGeometry.
The code in WorkArea.cpp only has to draw these shapes. The
CaretWidget (which never was a widget) in GuiWorkArea.cpp is gone
now.
As a consequence, the bounding box for the cursor is known precisely
and therefore rows should be repainted correctly now. This avoids
caret droppings.
Fixes bug #12024.
