Vadim Zeitlin dfd03f5fee Don't refresh wxStaticText if its label didn't really change
Optimize calling SetLabel() with the same label as the current one, this
seems to happen quite often in practice and results in flicker, so check
for it explicitly.

/**
@class wxStaticText
A static text control displays one or more lines of read-only text.
wxStaticText supports the three classic text alignments, label
ellipsization i.e. replacing parts of the text with the ellipsis ("...") if
the label doesn't fit into the provided space and also formatting markup
with wxControl::SetLabelMarkup().
@beginStyleTable
@style{wxALIGN_LEFT}
Align the text to the left.
@style{wxALIGN_RIGHT}
Align the text to the right.
@style{wxALIGN_CENTRE_HORIZONTAL}
Center the text (horizontally).
@style{wxST_NO_AUTORESIZE}
By default, the control will adjust its size to exactly fit to the
size of the text when SetLabel() is called. If this style flag is
given, the control will not change its size (this style is
especially useful with controls which also have the @c wxALIGN_RIGHT or
the @c wxALIGN_CENTRE_HORIZONTAL style because otherwise they won't make sense any
longer after a call to SetLabel()).
@style{wxST_ELLIPSIZE_START}
If the labeltext width exceeds the control width, replace the beginning
of the label with an ellipsis; uses wxControl::Ellipsize.
@style{wxST_ELLIPSIZE_MIDDLE}
If the label text width exceeds the control width, replace the middle
of the label with an ellipsis; uses wxControl::Ellipsize.
@style{wxST_ELLIPSIZE_END}
If the label text width exceeds the control width, replace the end
of the label with an ellipsis; uses wxControl::Ellipsize.
