<li>IMPROVED: JKQTPlotter::jkqtp_RESIZE_DELAY is thread-safe now (atomic)</li>
<li>IMPROVED: Using axis's tick label formating properties to format values in data-tooltips (e.g. dates will appear formated as such)</li>
<li>IMPROVED/REWORKED: reworked JKQTPErrorPlotstyle and error indicator plotting so error-inidcators can be specified as ORed combination of flags from JKQTPErrorPlotstyleElements, added additional error indicator styles (half-bars, arrows...)</li>
<li>IMPROVED/REWORKED: reworked JKQTPCADrawMode and coordinate axis drawing so the draw mide can be specified as ORed combination of flags from JKQTPCADrawModeElements, added flags to draw arrows at the end of the axis line</li>
<li>IMPROVED/REWORKED: coordinate axis code was refactored</li>
