Description (last modified by )
The DXF STYLE table contains information about text formatting, including width, obliqueness, text height, font name, bold and italic. From experimentation with AutoCAD it appears that most of these properties are only used as templates for newly-created TEXT entities, and not actually inherited to TEXT entities in the DXF (like DIMSTYLEs). But font name, bold and italic appear to be exceptions to this.
Currently OGR outputs the text style name in the f parameter of the style string. This is wrong; f is for the font name. I correct this behaviour in the patch. If no font name is available, "Arial" continues to be used as the fallback.
This patch also adds support for bo (bold), it (italic) and w (width factor) style parameters.
Additionally, it fixes a bug where a TEXT entity with alignment point x-coordinate (group code 11) equal to 0 would be missing the dx parameter in the style string, even when that parameter would have been nonzero. Likewise for the y-coordinate.
