Detailed Description

Store a TextRecord.

This consists of style information and a number of glyphs. This may be parsed from a SWFStream, or it can be constructed dynamically by TextField. A static TextField has fewer possible properties than a dynamic one.

	)		`[static]`

Render the given glyph records.

Display of device fonts is complicated in Gnash as we use the same rendering process as for embedded fonts. The shape and position of a font relies on the concatenated transformation of its containing DisplayObject and all parent DisplayObjects. Device fonts have the peculiarity that the glyphs are always scaled equally in both dimensions, using the y scale only. However, indentation and left margin (the starting x position) *are* scaled using the given x scale. The translation is applied as normal. The proprietary player does not display rotated or skewed device fonts. Gnash does.

Read a TextRecord from the stream.

Parameters:

in	The SWFStream to read from.
m	The movie_definition containing this TextRecord.
glyphBits	The number of bits per glyph
advanceBits	The number of bits per advance
tag	The tag type of this TextRecord. This must be DefineText or DefineText2
