wxWidgets/include/wx/richtext/richtextformatdlg.h
Julian Smart 32423dd824 Added pixel size capability to wxTextAttr and wxRichTextCtrl.
Fixed composite object positioning in centred and right-aligned
paragraphs.
Added field example to sample, and enabled pixel font size selection.
Added custom text and dimension scaling.
