\twocolitem{{\bf Option}}{{\bf Value}}
\twocolitem{no-maskblt}{1 to never use WIN32's MaskBlt function, 0 to allow it to be used where possible. Default: 0.
-
In some circumstances the MaskBlt function can be slower than using the fallback code, especially if using
-DC cacheing. By default, MaskBlt will be used where it is implemented by the operating system and driver.

+DC cacheing. By default, MaskBlt will be used where it is implemented by the operating system and driver.}
+\twocolitem{msw.remap}{If 1 (the default), wxToolBar bitmap colours will be remapped
to the current theme's values. Set this to 0 to disable this functionality, for example if you're using
more than 16 colours in your tool bitmaps.}
-\twocolitem{mgl.aa-threshold}{(wxMGL only) Set this integer option to point
-size below which fonts are not antialiased. Default: 10.
-}
-\twocolitem{mgl.screen-refresh}{(wxMGL only) Screen refresh rate in Hz.
-Reasonable default is used if not specified.
-}
+\twocolitem{msw.window.no-clip-children}{If 1, windows will not automatically get the WS\_CLIPCHILDREN
+style. This restores the way windows are refreshed back to the method used in versions of wxWidgets
+earlier than 2.5.4, and for some complex window hierarchies it can reduce apparent refresh delays. You may
+still specify wxCLIP\_CHILDREN for individual windows.}
+\twocolitem{msw.notebook.themed-background}{If set to 0, globally disables themed backgrounds on notebook
+pages. Note that this won't disable the theme on the actual notebook background (noticeable only if there are no
+pages).}
+\twocolitem{msw.staticbox.optimized-paint}{If set to 0, switches off optimized wxStaticBox painting.
+Setting this to 0 causes more flicker, but allows applications to paint graphics on the parent of a static box
+(the optimized refresh causes any such drawing to disappear).}
+\twocolitem{msw.display.directdraw}{If set to 1, use DirectDraw-based implementation of
+\helpref{wxDisplay}{wxdisplay}. By default the standard Win32 functions are
+used.}
+\twocolitem{msw.font.no-proof-quality}{If set to 1, use default fonts quality
+instead of proof quality when creating fonts. With proof quality the fonts
+have slightly better appearance but not all fonts are available in this
+quality, e.g. the Terminal font in small sizes is not and this option may be
+used if wider fonts selection is more important than higher quality.}

+method normally tries to detect automatically whether transparency for top
+level windows is currently supported, however this may sometimes fail and this
+option allows to override the automatic detection. Setting it to $1$ makes the
+transparency be always available (setting it can still fail, of course) and
+setting it to $0$ makes it always unavailable.}
+\twocolitem{gtk.desktop}{This option can be set to override the default desktop
+environment determination. Supported values are \texttt{GNOME} and \texttt{KDE}.}
+\twocolitem{gtk.window.force-background-colour}{If 1, the backgrounds of windows with the wxBG\_STYLE\_COLOUR background style are cleared forcibly instead
+of relying on the underlying GTK+ window colour. This works around a display problem when running applications under KDE with the gtk-qt theme installed (0.6 and below).}

+Returns \true if the option with the given \arg{name} had been set to $0$

+\texttt{GetOptionInt(name) == 0} as this would also be true if the option
