to continue searching for a suitable font rather than just failing
on the first. Also add limitFontWidth to allow changing the amount
by which a glyph must extend outside the font's bounding box to
disallow it.

* corrected an error-handling case in decodeUtf8, matching a similar fix in patch #268
* add a test-driver for ptydata.c
* minor cleanup of macros
* fix some errata in ctlseqs.ms
* allow immediate repaint-on-palette-changed if double-buffering is enabled.

* modify DECERA color for consistency with other erasures/clearing
* ECH should not be masked by DECSCA
