Patch #347 - 2019/06/30
* fix a few minor bugs found with Coverity.
* improve double-buffering for scrollbars combined with scrolled
text; add bufferedFPS resource to control the maximum rate of
screen updates (report by Mike Thornburg).
* improve fixes for DECCRA handling of double-width characters (patch
by Martin Hostettler).
* improve discussion of ECMA-48's typographical error for SD in
ctlseqs.ms (prompted by report by Martin Hostettler).
* correct off-by-one in parameter limit-check for DECCRA (report by
Martin Hostettler).
* modify saveCellData to handle case where double-width character is
partially copied; that should be blanked (report/testcase by Thomas
Wolff).
* add resource buffered to allow enabling/disabling double-buffered
mode.
* two fixes for the double-buffer configuration, prompted by
MacPorts' switch to double-buffering (patch by Mike Thornburg,
MacPorts #58313):
+ ensure that the needSwap flag is set after drawing TrueType
text
+ corrected the drawable-parameter used for the bar-cursor
* modify ScrnRefresh to ignore a case where the left/right halves of
a double-width character have been set to different video
attributes. The attribute to use is in the left-half
(report/testcase by Thomas Wolff).
* correct a limit-check for DECCRA in case the target lies off-screen
(report/testcase by Thomas Wolff).
* documentation errata (report by Thomas Wolff).
* reset flags including wraparound and reverse-wrap when switching to
VT52 mode, while noting that DEC's standard documention leaves that
behavior undefined (report by Thomas Wolff).
* ensure that italic font is turned off on hard/soft resets (report
by Martin Hostettler).
* improve responsiveness to X events while processing HTML or SVG
dumps (report by Martin Hostettler).
* replace logic in wcwidth.c for detecting double-width characters
with binary-search table generated using updated uniset (report by
Robert Ross).
* add test-driver for wcwidth.c to simplify comparison with system's
wcwidth.
* ensure that window-manager name comparisons work when active-icon
is enabled, since CSI13t uses the window-manager name (Arch
#62818).
* trim a stray “experimental” in one of the comments about the
tcap-query feature, which has been a supported feature since 2008
(see patch #238).
