[PATCH v5 0/5] MR7812: win32u: Add more CompAttr, CompClause implementation using cursor_begin, cursor_end concept.
If CompAttr and CompClause are properly configured, Japanese input will be more comfortable.
Inspired by cursor_begin and cursor_end from Wayland zwp_text_input_v3:: preedit_string, I extended the cursor_pos concept as follows:
cursor_pos = MAKELONG( cursor_begin, cursor_end );
ime_to_tascii_ex() uses this to construct CompAttr, CompClause. MS Windows native CompAttr, CompClause is a bit more complicated than this, but the concept is useful enough.
It requires additional implementation in the Wine ime_ui_window proc and richedit control. However, it is useful for applications that inline ime composition string.
This can be tested with MS Office Word, Excel. LANG=ja_JP.UTF-8 wine EXCEL.EXE
Test key sequences: - “n-i-h-o-n-g-o-n-o-m-o-j-i-d-e-s-u-.-SPACE”. - And, RIGHT, LEFT, Shift+LEFT, Shift+RIGHT, ESC, SPACE, etc.
-- v5: winex11: Update only when caret pos changed in xic_preedit_caret. winex11: Extend cursor_pos using cursor_begin, cursor_end. winemac: Extend cursor_pos using cursor_begin, cursor_end. winewayland: Extend cursor_pos using cursor_begin, cursor_end. win32u: Add more CompAttr, CompClause implementation using cursor_begin, cursor_end concept.

v3: drop negative cursor value code.
I've tested fixing the comp_clause length to 4 and didn't find any problems. Imagining the application code, I think it should be fine. Nevertheless, I can't be sure that there are no applications written in an unusual way.
The actual MS clause concept is more complex and may have comp_clause larger than 4. If we can extend the concept further in the future, I think we'll need something like get_comp_clause_count, set_comp_clause, set_comp_attr.
