Add starting point for Arabic lots

These macros were defined in 2.38, but SWE-GLib depends on
2.32. Requiring a newer version solely for this would be an overkill, so
let’s just backport them.

+## Bindings

+SWE-GLib utilizes

 ## Usage
 
-Many functions return non-opaque C structs; their documentation can be found inline, and in the generated GTK-Doc. Unless otherwise stated, the returned values should never be freed.

-2 arc seconds is about 0.000555 degrees of error, which is, well, kind of small. Of course, if you need very precise horoscopes or need planetary positions for a totally different thing, you should really provide a (close to) exact value; otherwise, it is safe to pass any value (well, which seems logical: the average level of all dry lands is about 840 meters; the average level of the whole planet Earth (including oceans and seas) is around 280 meters. Providing a value of ~400 should be OK most of the time).

 ## API stability
 
-The project is currently marked as 1.0. This means that API and ABI changes are very unlikely to happen.
+The project is currently transitioning to 2.0. master is a bit fragile
+at the moment, 1.x versions are considered to be stable (although see
+commit 8f52aba about a huge typo-bug).
 
 ## Limitations
 
 ### Topocentric calculations only
 
-Although the original Swiss Ephemeris library supports it, SWE-GLib can't do Heliocentric, nor Geocentric (as seen from the center of Earth) calculations, only Topocentric (as seen from a given point on Earth"s surface) calculations yet.

 ### Database size
 
-The size of all data files provided by Astrodienst is around 40MB. Although it should not be a problem with today's home hardware, it can be a hard requirement on embedded systems. For basic calculations, keeping the following files under $(datadir)/swe-glib is usually enough:

 ### Fixed stars are not known yet
 
-Although Swiss Ephemeris has the functionality to calculate the position of fixed stars, SWE-GLib doesn't provide such functionality. This, however, is a planned feature for the close future.

+
+As the underlying Swiss Ephemeris is published under GPL (or a
+commercial license I can not afford), SWE-GLib is also uses that. This
