perf ui browser: Abstract some more slang operations

Browsers don't have to deal with absolute coordinates, just using (row,
column) and leaving the rest to ui_browser is better and removes one
more UI backend detail from the browsers.

Also shorten the percent_color setting idiom, removing some more direct
libslang calls.
