Add a cache for converted image files. This needs to be enabled in the
preferences file with \use_converter_cache true. It is disabled by default, and no GUI support for changing the preferences is yet implemented. * src/insets/insetgraphics.C (InsetGraphics::prepareFile): Use image file cache * src/insets/ExternalSupport.C (updateExternal): Use image file cache * src/exporter.C (Exporter::Export): Do not use image file cache * src/graphics/GraphicsCacheItem.C (CacheItem::Impl::imageConverted): Add the converted file to the image file cache (CacheItem::Impl::convertToDisplayFo): Use image file cache * src/converter.C (Converters::convert): Use image file cache if the caller allowed that * src/converter.h (Converters::convert): Adjust arguments * src/Makefile.am: Add new files * src/support/lyxlib.h (chmod): new function (copy): add mode argument * src/support/copy.C (chmod): new function (copy): implement mode argument * src/support/mkdir.C (lyx::support::mkdir): Add warning if permissions are ignored * src/lyxrc.[Ch]: Add new settings \converter_cache_maxage and \use_converter_cache * src/ConverterCache.[Ch]: New image file cache * src/importer.C (Importer::Import): Do nut use the image file cache * src/lyx_main.C (LyX::init): Initialize the image file cache * src/mover.[Ch] (Mover::do_copy): Add mode argument (SpecialisedMover::do_copy): ditto * configure.ac: Check for chmod * development/cmake/ConfigureChecks.cmake: ditto * development/cmake/config.h.cmake: ditto * development/scons/SConstruct: ditto * development/scons/scons_manifest.py: Add new files git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@15897 a592a061-630c-0410-9148-cb99ea01b6c8
