45b8c20059 [poincare/layout] Fix XNT when cursor points outside of integrand 
Example:
   3
  sum(|4) and XNT event gives n
  n=1

   3
 |sum(4) and XNT event gives 0
  n=1

93832549f1 [poincare] childNeedsUserParentheses takes childIndex param 
Scenario:
0+exp^0 i->b
0+exp b^0 i->b
Go to VariableBox/expression -> Parentheses were not properly added when
b was replaced

e09e36a57f [poincare] When replacing symbols, if it contains itsef return undef 
Circularly defined functions/symbols are detected more quickly, which
prevents some tree pool exhaustions.
For instance, with f(t) = [[f(t)][f(2t)]]

eb0f6153c5 [poincare] When reducing expressions, we check if an expression is a 
matrix to know if it can be permuted in a multiplication for example.
This check has to be 'recursive'/'deep' to detect cases like "cos(3×confidence(cos(2)/25,3))"
