Subject: Prevent segfault in draw_key_config (#2)
X-Git-Url: https://notaz.gp2x.de/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e7f580052c03fa3f4603051c1b718be4bd8b2db7;p=libpicofe.git

Prevent segfault in draw_key_config (#2)

Its calculated `y` value can dip below zero
This causes a segfault if used as an argument of `text_out16`
