This required major changes to font management, since I needed to expose font design metrics to obtain underline information. I simplified the RS_Font structure and added font metric information to it. Changed the font matching APIs to no longer use just a string to identify fonts. Instead, the font object is now passed around all the way down to DrawString.

Having exposed font metrics, I then implemented text underlining for both the simple labels and curved labels, for both the simple and the tiled map label renderers -- a total of 4 similar but different implementations.

Also removed "inline" from a couple of functions in DWFRenderer. Those were confusing the release build on Linux.

Revised the text alignment computation code in both LabelRenderers to use the newly available font metrics instead of guessing about ascenders and descenders.
