 *  [ES] added INT(x,y) evaluating integral value of y dx
 *  [ES] added RSUM(vexpr) - running sum

  Bug fixes

 *  [ES] fixed memory corruption when reading in block data (rep. #1258). The
         bug was introduced in 5.1.11

         the graph didn't exist (including reps. #886 and #1267)
 *  [ES] removed extraneous accent glyphs in the 0x9? range of IsoLatin1 and
         IsoLatin2 encodings (including rep. #1269)

         (rep. #1276)

5.1.11
  Functionality

 *  [ES] hotlinks now work for all set types (rep. #572)
 *  [ES] updating hot-linked sets now works for all graphs, not the current
         one only
 *  [YZ] added encoding files for Russian codepages koi8-r and cp1251 and for
         Ukrainian codepage koi8-u

  Interface

 *  [ES] use "+"/"-" instead of \ 
"shown"/"hidden" in the graph selectors

  Parser

 *  [ES] added UPDATEALL command, equivalent of "View/Update all"

  Drivers

 *  [ES] set resolution in the PNG output (rep. #1225)

  Portability/Compilation

  Bug fixes

 *  [SR] precision used for special tick locations was insufficient
         (rep. #1228)
 *  [ES] referring to "S_" in the parser with no sets in the current \ 
project
         crashed the app
 *  [ES] GraceIsOpen() from the grace_np library returned true after the Grace
         process exited (rep. #922)
 *  [ES] excluded .cvsignore files from source tarballs (rep. #1248)
 *  [ES] a minor memory leak fixed (40 bytes per set import/reading in)
 *  [ES] configure --with=f77=/absolute/path/to/f77 was broken (rep. #1243)
 *  [ES] in XY charts, explicitly check that abscissas of all sets are the same
