Add FT_Get_PS_Font_Value() API.

Browse Source 
This allows a Type 1 font face to be interrogated to retrieve most
of the dictionary keys (keys not relevant to FreeType's Type 1
interpreter are not available).

* include/freetype/internal/services/svpsinfo.h
(PS_GetFontValueFunc): New typedef.
(PSInfo): Add `ps_get_font_value'.
(FT_DEFINE_SERVICE_PSINFOREC): Updated.

* include/freetype/internal/t1types.h (T1_EncodingType): Moved to...
* include/freetype/t1tables.h: Here.
(PS_Dict_Keys): New enumeration.
(FT_Get_PS_Font_Value): New declaration.

* src/base/fttype1.c (FT_Get_PS_Font_Value): New function.

* src/type1/t1driver.c (t1_ps_get_font_value): This new function
does the real job.
(t1_service_ps_info): Add it.

* src/cff/cffdrivr.c (cff_service_ps_info), src/cid/cidriver.c

* @function:
* FT_Get_PS_Font_Value
*
* @description:
* Retrieve the value for the supplied key from a PostScript font.
*
* @input:
* face ::
* PostScript face handle.
*
* key ::
* An enumeration value representing the dictionary key to retrieve.
*
* idx ::
* For array values, this specifies the index to be returned.
*
* value ::
* A pointer to memory into which to write the value.
*
* valen_len ::
* The size, in bytes, of the memory supplied for the value.
*
* @output:
* value ::
* The value matching the above key, if it exists.
*
* @return:
* The amount of memory (in bytes) required to hold the requested
* value (if it exists, -1 otherwise).
*
* @note:
* The values returned are not pointers into the internal structures of
* the face, but are `fresh' copies, so that the memory containing them
* belongs to the calling application. This also enforces the
* `read-only' nature of these values, i.e., this function cannot be
* used to manipulate the face.
*
* `value' is a void pointer because the values returned can be of
* various types.
*
* If either `value' is NULL or `value_len' is too small, just the
* required memory size for the requested entry is returned.
*
* The `idx' parameter is used, not only to retrieve elements of, for
* example, the FontMatrix or FontBBox, but also to retrieve name keys
* from the CharStrings dictionary, and the charstrings themselves. It
* is ignored for atomic values.
*
* PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To
* get the value as in the font stream, you need to divide by
* 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
*
* IMPORTANT: Only key/value pairs read by the FreeType interpreter can
* be retrieved. So, for example, PostScript procedures such as NP,
* ND, and RD are not available. Arbitrary keys are, obviously, not be
* available either.
*
* If the font's format is not PostScript-based, this function returns
* the `FT_Err_Invalid_Argument' error code.
*
