Addendum to commits 5f4bb73e and c6ccb92b.
- GetLocaleInfo() returns an int, not a bool: makes it clear in the test.
- No need to use StringCchCopy() to just initialize two chars to the
same value.
- The question about the test in https://github.com/reactos/reactos/pull/4723#discussion_r981331634
was meant to discover that CreateDIBSection() was unnecessary, since
the very original code (before commit 0991cedc) did not use it and was
working fine in that regard. The simple fix was to use GetDC(NULL).
- Use SM_CXSMICON/SM_CYSMICON metrics for the KBSWITCH indicator as well.
- Override the font size obtained from SPI_GETICONTITLELOGFONT with a
known one (allows to get a correct indicator even if the user font
is very large).
- Do the initialization in such a way that in case SPI_GETICONTITLELOGFONT
or CreateFontIndirect fails, we always fall back to the default stock
font that is ensured to always exist.
- Initialize *all* the fields of the IconInfo structure.
- Fix IntLoadKeyboardLayout function to return the correct HKL value.
- Modify LAYOUT_LIST_NODE structure to add more information.
- Fix LayoutList_GetByHkl function to choose the IME HKLs correctly.
- Ignore DELETED entries correctly.
- Improve UI/UX.
