 *                       Render FormFeilds on a page to a device independent bitmap.                     
 * Parameters:
-*                       hHandle         -       Handle to the form fill module. Returned by FPDFDOC_InitFormFillEnviroument.
+*                       hHandle         -       Handle to the form fill module. Returned by FPDFDOC_InitFormFillEnvironment.
 *                       bitmap          -       Handle to the device independent bitmap (as the output buffer).
 *                                                       Bitmap handle can be created by FPDFBitmap_Create function.

 *                       start_x         -       Left pixel position of the display area in the device coordinate.
 *                       start_y         -       Top pixel position of the display area in the device coordinate.
 *                       size_x          -       Horizontal size (in pixels) for displaying the page.
 *                       size_y          -       Vertical size (in pixels) for displaying the page.
 *                       rotate          -       Page orientation: 0 (normal), 1 (rotated 90 degrees clockwise),
 *                                                               2 (rotated 180 degrees), 3 (rotated 90 degrees counter-clockwise).
 *                       flags           -       0 for normal display, or combination of flags defined above. 
 * Return Value:
 *                       None.
 * Comments: 
 *                       This method is designed to only render annotations and FormFields on the page. 
 *                       Without FPDF_ANNOT specified for flags, Rendering functions such as FPDF_RenderPageBitmap or FPDF_RenderPageBitmap_Start will only render page contents(without annotations) to a bitmap.
 *                       In order to implement the FormFill functions,Implementation should call this method after rendering functions finish rendering the page contents.
