Revert "[DefineTextTag] Honour TextMatrix"

This reverts commit fdbfe15e70ca3886b553869866d44a70b9f2f0fd.

This was a wrong way to support TextMatrix. DisplayObject::setMatrix()
is only for legacy transformation (from PlaceObject2).
[DefineTextTag] Proper support for TextMatrix

Apply TextMatrix directly to the glyph shapes.
[PlaceObject2Tag] Ignore non-DisplayObjects

Bug 1109065 has a file that adds a DefineFont tag using PlaceObject2.
