[geany/geany] 19336d: Update Scintilla to version 5.3.7

Branch: refs/heads/master Author: Thomas Martitz thomas.martitz@mailbox.org Committer: Thomas Martitz thomas.martitz@mailbox.org Date: Wed, 04 Oct 2023 19:47:07 UTC Commit: 19336d22946b77bbcb5131544ea0e6317cdcf6b5 https://github.com/geany/geany/commit/19336d22946b77bbcb5131544ea0e6317cdcf6...

Log Message: ----------- Update Scintilla to version 5.3.7

Notable changes since 5.1.5 - multithreaded layouting and line wrapping. Neil says this can lead to dramatic improvements. Disabled by default, see SCI_SETLAYOUTTHREADS (i.e. we don't use it yet) - New APIs to support 64-bit document positions on Win32: SCI_GETSTYLEDTEXTFULL, SCI_GETTEXTRANGEFULL, SCI_FINDTEXTFULL, and SCI_FORMATRANGEFULL We should move should move to these APIs, as the predecessors will be deprecated sooner or later. Not sure if it affects GTK-backend on win32 as well? - Change bar (will be enabled in a separate commit)

Also update Lexilla to 5.2.7, changes since 5.1.4: - Tons of LexBash improvements - Also numerous improvements to languages (Ruby, Matlab, F# and many more)
