Detailed Description

The SmTextureText2 node is used for fast text rendering.

This node can render ~200k strings / second. It pregenerates a font texture which is used for rendering the text instead of using the glBitmap()/glPixmap() method.

It can be used in two modes. If multiple 'position' values are specified, one string is rendered at each position. If a single 'position' value is supplied, the strings will be rendered vertically like the SoText2 node.

This node also supports material binding and will pick materials from the state whenever the material binding != OVERALL.

If the stringIndex field is not empty, it will be used to select strings to render. If the material binding != OVERALL, the index array will also be used to select the color.
