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).
