A change in overflow mode requires calculation of the text size and resetting
the overflow shader

Subsequent operations like debugAssertDoesMeetConstraints() may do layout
operations that alter _textPainter's state.

The first hot reload does a bunch of work that we used to hide behind the
loader screen. This PR changes the messsage printed to the user on the first
reload from:

'Performing hot reload...'

to:

'Initializing hot reload...'

Subsequent reloads say 'Performing hot reload...'

Also switches to single quotes for consistency with surrounding code.
