5cd81a980e Codechange: Store both left and right glyph positions in a run. 
This also allows the end of a run to be known without using an extra position entry.

80ddcb9d7d Codechange: Move GetCharPosInString/GetCharAtPosition to gfx_layout.

3d4b98845a Codechange: Remove initial colour from layouter cache. (#12728) 
Initial colour is now always TC_INVALID, which is substituted with the desired colour when drawing the layout line.

This allows strings which differ only by initial colour to use the same layout cache entry, increasing the efficacy of the cache.

676d64037d Fix d6ccfdb: GetCharPosition failed for RTL text. (#12710)

6d276698b6 Fix: Memory leak in ICUParagraphLayout::NextLine() (#11895) 
This function calls icu::BreakIterator::createLineInstance() but does not clean up after it.

Instead use a static instance that is cloned (for thread-safety) and deleted as necessary.

d6ccfdbbd9 Fix #11827: Make Layouter::GetCharPosition() aware of ligatures. (#11831) 
When ligatures happen the precise individual character position is not known, so instead return the previous position (which is that of the ligature.)

60399e17bd Codechange: C++-ify the Layouter and related functions 
They all now access a std::string_view, instead of a "const char *"
or std::string (in some cases).

Additionally, GetCharAtPosition and friends now return an index
instead of a "const char *", as it makes for a more clear interface.

81d4fa6999 Feature: drop ICU-lx in favour of directly interfacing with harfbuzz 
This means we have RTL support again with ICU 58+. It makes use of:
- ICU for bidi-itemization
- ICU for script-itemization
- OpenTTD for style-itemization
- harfbuzz for shaping

ac4a7d02c7 Codechange: Improve LineCache queries (#9417) 
Adds the support to query the linecache without copying the string.
This uses a custom transparent comparator in conjunction with
a query type using a std::string_view.
