Description
get_font_extentsget_font_extentsGetFontExtentsGetFontExtentsGetFontExtentsget_font_extents queries the maximum width
(MaxWidthMaxWidthMaxWidthMaxWidthmaxWidthmax_width), height (MaxHeightMaxHeightMaxHeightMaxHeightmaxHeightmax_height), and extension
above and below the baseline (MaxAscentMaxAscentMaxAscentMaxAscentmaxAscentmax_ascent and
MaxDescentMaxDescentMaxDescentMaxDescentmaxDescentmax_descent, respectively) of the font that is currently set
for the window WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle. The sizes are measured in
