• disable SIXEL aspect-ratio, pending a rewrite (patch by Ben Wong).
• add resource incrementalGraphics (prompted by patch by Ben Wong).
• reorganize graphics_sixel.c as a step toward eliminating graphics buffer-size (integrated patch by Ben Wong).
• use linux consistently rather than the older linux.
• build-fix for musl (report by Jonáš Vidra, adapted patch by Khem Raj):
  • modify ifdef for USE_OPENPTY, changing test for GLIBC to linux
  • change ifdef's for _POSIX_SOURCE to _POSIX_VERSION

• minor consistency fixes for manpage.
• fix regression in patch #390: non-UTF8 text pasted as a XA_UTF8_STRING was not decoded (report by Petri Kaukasoina).
