+[PATCH] Add serdisplib driver
+
+This patch adds a serdisplib driver for the serdisplib library
+(http://serdisplib.sf.net) that is used for low-level accessing of dot-matrix
+devices (i.e. such displays that are drived by pixel and not by characters
+unlike HD44780, for example).
+
+I know there's already glcdlib. But that approach has several disadvantages:
+
+ o Unnecessary library dependencies.
+ o Complicated installation, i.e. you have to edit two configuration files.
+ o Too much redraws. In fact, that was the reason for me to write this
+ driver because my ctinclud display (http://www.ct-maeusekino.de) was quite
+ unusable with the glcdlib driver. The problem is simply that lcdproc
+ redraws the whole screen each second and it's the task of the driver
+ to not to redraw it in reality. The problem is now that the glcdproc
+ driver only has the view of characters, and cannot decide which pixels it
+ actually has to redraw. And graphlcd which has the per-pixel view doesn't
+ do that "caching" and simply redraws all. Of course, that _can_
+ be changed in graphlcd, but I'm sure that leads to endless discussions and
+ because I didn't like the glcdlib -> graphlcd -> serdisplib approach
+ anyway, I decided to write that driver.
+
+Some important design decisions:
+
+ o The driver is split into lcdgraphic.c and serdisplib.c. All function that
+ do the character -> pixel "rendering" are split out into lcdgraphic.c,
+ so it would be possible to write another low-level driver that uses that
+ function. However, in normal cases it makes more sense to add that part to
+ serdisplib.
+ o It only requires FreeType (http://freetype.sf.net) for font rendering.
+ That's no new real dependency because in almost all cases, graphlcd was
+ compiled with FreeType support.
+ o Only mono space fonts are supported.
+ o The driver implements symbols (arrow, etc.) using Unicode characters of the
+ font. (The recommended font is Andale Mono which is available for free
+ from http://corefonts.sf.net)
+ o Works on i686 and x86_64.
+
+Please review. The patch is against 0.5.2. If you consider to add this into
+CVS, I'll provide documentation. And this time, I'll provide the documentation
+in time unlike with the ula200 driver. ;-)
