     *
     *
     * I've tried to make this more reasonable, but I've run in to a lot
     * of nonsense.
     *
     * The original issue is the code was written in pixels and not
     * dialog units (DLUs). All DialogBox functions use DLUs, which
     * vary based on the selected font (yay).
     *
     * According to MSDN, the most reliable way to convert is via
     * MapDialogUnits, which requires an HWND, which we don't have
     * at time of template creation.
     *
     * We do however have:
     *  The system font (DLU width 8 for me)
     *  The font we select for the dialog (DLU width 6 for me)
     *
     * Based on experimentation, *neither* of these return the value
     * actually used. Stepping in to MapDialogUnits(), the conversion
     * is fairly clear, and uses 7 for me.
     *
     * As a result, some of this is hacky to ensure the sizing is
     * somewhat correct.
     *
     * Honestly, a long term solution is to use CreateWindow, not CreateDialog.
     *

     *
     * In order to get text dimensions we need to have a DC with the desired font.
     * I'm assuming a dialog box in SDL is rare enough we can to the create.
