* @function:
*FT_OpenType_Validate
*
* @description:
*Validate various OpenType tables to assure that all offsets and
*indices are valid.The idea is that a higher-level library that
*actually does the text layout can access those tables without
*error checking (which can be quite time consuming).
*
* @input:
*face ::
* A handle to the input face.
*
*validation_flags ::
* A bit field that specifies the tables to be validated.See
* @FT_VALIDATE_OTXXX for possible values.
*
* @output:
*BASE_table ::
* A pointer to the BASE table.
*
*GDEF_table ::
* A pointer to the GDEF table.
*
*GPOS_table ::
* A pointer to the GPOS table.
*
*GSUB_table ::
* A pointer to the GSUB table.
*
*JSTF_table ::
* A pointer to the JSTF table.
*
* @return:
* FreeType error code.0~means success.
*
* @note:
* This function only works with OpenType fonts, returning an error
* otherwise.
*
* After use, the application should deallocate the five tables with
* @FT_OpenType_Free.A NULL value indicates that the table either
* doesnt exist in the font, or the application hasnt asked for
* validation.
