wxSlider with wxSL_LABELS style but without wxSL_MIN_MAX_LABELS didn't show the current value because the width of the value label was 0. Fix this by always computing the widths of min and max labels and using the longest of them for the value label, even if we don't actually show them. Closes #13291. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@68230 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
