keysym: fast path for case sensitive xkb_keysym_from_name xkb_keysym_from_name() is called a lot in Compose file parsing. The lower case handling slows things down a lot (particularly given we can't use the optimized strcasecmp() due to locale issues). So add separate handling for the non-case-sensitive case which is used by Compose. To do this we need to add another version of the ks_tables table. This adds ~20kb to the shared library binary. We can probably do something better here but I think it's fine. Signed-off-by: Ran Benita <ran@unusedvar.com>
