Measures the area occupied by a text string with the specified alignments, flag, and current font, on the canvas.
MeasureText is implemented by the TCanvas descendants to determine the rectangle area occupied by a text string with the specified wrapping, alignments, flag, and current font. The string text is framed in a rectangle.
The ARect parameter specifies the bounding rectangle of the text. ARect is the return variable. If ARect is not initialized, the returned rectangle is centered in (0,0).
