The constructor built QRegularExpression("[^A-Z]") on every call, and
compiling it cost more than the rest of Diagram::convertPosition() put
together -- about 95k instructions a call under callgrind. Every element
row of the project database pays it on each rebuild, as does anything
else that turns a scene point into a folio cell.
