By creating a bitmap from the SDL_Surface and painting that using a buffered
paint DC. See code below.
mCanvas is a 24-bit RGB surface created with SDL_CreateRGBSurface. This
needs to be in OnPaint.

        // create a bitmap from our pixel data
        wxBitmap bmp(wxImage(mCanvas->w, mCanvas->h,
                             static_cast<unsigned char *>(mCanvas->pixels),
true));

        // paint it
        wxBufferedPaintDC dc(Panel, bmp);
