SWF Text Entry (swf_text_entry)

struct swf_text_entry {
	unsigned		f_glyph_index : f_glyph_bits;
	signed			f_advance : f_advance_bits;
};

The swf_text_entry structure defines a list of characters and the number of TWIPs to skip to go to the next character. Note that f_advance is a signed value. Thus you can write characters from right to left which is useful to write characters in languages such as Arabic in a native way. The number of bits used to define each field of this structure is defined in the DefineText or DefineText2 tags.
