JKQTMathText: improved placement of sub-/superscript nodes by using JKQTMathtextNodeSize::baselineXCorrection to shift subscript to the left for e.g. preceding italic text or symbols that require such a shift
...
JKQTMathText: moved sub-/superscripts placed below/above a bit further apart from the central symbol/node

JKQTMathText: Code Cleanup: using JKQTMathTextNodeSize for all size-calculation functions and got rid of all functions that take the output parameters with call-by-reference
...
JKQTMathText: JKQTMathTextBraceNode now properly supports different opening and closing braces e.g. |...> for bra-vetors

code cleanup: Removed Parameter prevNodeSize from JKQTMathTextNode::draw() and JKQTMathTextNode::getSize()/JKQTMathTextNode::getSizeInternal(), since it is only really necessary for JKQTMathTextSubscriptNode and JKQTMathTextSuperscriptNode
...
bugfixed possible crash in JKQTMathTextWhitespaceNode (QMap[n1]=QMap[n2]=something; does not work for some reason)

bugfix: JKQTMathText: \sum and \prod used the wrong symbol in XITS-mode
...
NEW: JKQTMathText: \limits and \nolimits work as in LaTeX now (before it was simply removed and the functionality implemented for a fixed list of symbols)
remove/breaking: JKQTMathText: \v[a-zA-Z] and shorthand for \vec{a-zA-Z} was removed
improvement: improved typesetting of sub-/supercripts, especially for large math operators and braces

MODIFIED: brace node now calculates the extension of the child height above or below the strikeoutPos, in order to center braces around the strikeoutPos
...
fixed: strikeoutPos was not correctly calculated in sub-/superscript node
NEW: JKQTMathText shows strikeoutPos when drawing Debug-Boxes
