Got rid pf superfluous redirection to deprecated functions of ST_GeomFromWkb and ST_GeomFromText - now they just point directly to the c functions. Changed all FromWKB, FromText variants to point to the non-deprecated ST_GeomFrom, ST_BuildArea etc. (before they were pointing at deprecated functions)

Move over ST_Collect and ST_Union, provide examples for ST_Union. Get rid of comment about don't use ST_Union with geometry collections - seems to work fine with those.

moved over st_centroid and provided examples in both svg and png format. Eventually, ImageMagick will be used to generate the png files, but for now they are committed into svn.

Allow Makefile substitutions for PGCONFIG which are required if pg_config is not located in the path. Note that as part of this fix, we now need to generate topology/Makefile using autoconf. Thanks to Jorgen Austvik for the report and partial patch.

Add PROJ.4 version check to ensure that a minimum version of 4.5.0 is installed. This is to ensure that the pj_set_searchpath() function is present (note: it was actually added in 4.4.9, however we version detect on major.minor rather than major.minor.release)

Started migration of the functions in reference.xml using the <variablelist> concept to a new "reference_new.xml" using DocBook's <refentry> concept. Once migration is complete, reference.xml will be removed and reference_new.xml will be renamed to reference.xml. The included template.xml file is not used, except to provide example usage of DocBook's refentry tag.

Apply some autoconf / Makefile changes from Olivier Courtin. XSLBASE should not be checked for validity unless it has been explicitly specified using the --with-xsldir option, and we also add some friendlier messages in the documentation Makefile in case the DocBook stylesheets and/or xsltproc cannot be found. Additionally, the configure --help output has been tidied up using the AS_HELP_STRING macro.

More work on improving the EWKT/B parser; remove all references to allocator functions from outside of liblwgeom by generating wrapper functions with more meaningful names. As well as cleaning up the API, it also makes the code much more readable

Numerous small changes. Changed some returns 1 (TRUE) to just TRUE. Automatic casting between 0 1 and boolean no longer exists in PostgreSQL. Lets not confuse people by suggesting to them they are the same.

fixed ST_Dimension example, flipped order of conditions in WHERE on some examples (in later versions of PostgreSQL since we don't have our costs right - the planner may choose to process in order of conditions
Add the parser build rules back into the liblwgeom Makefile, so now any changes to either the lexer or parser source files will automatically invoke a rebuild of the relevant output files during make
Fix liblwgeom requiring gcc to compile. By using macros and variables supplied by libtool, we can now detect the PIC flags and whether the compiler will accept additional gcc warning flags for developers

Split the basic geometry accessors into a separate static library liblwgeom.a; this potentially allows re-use of the liblwgeom functions from within PostGIS, or could be extended at a later date to include databases other than MySQL. This patch includes a change to the liblwgeom handler functions; instead of sprinkling init_pg_func()s around the source, I have changed the default liblwgeom handlers to make use of a callback to allow linked libraries to set their own handlers the first time any of them are called. I have also tidied up the parser API a little in liblwgeom.h, which means wktparse.h can be removed from all of the headers in the lwgeom/ directory, plus renamed wktunparse.c to lwgunparse.c to keep things similar to lwgparse.c. Finally, I renamed liblwgeom.c to lwutil.c to avoid confusion within the new interface. TODO: the liblwgeom Makefile has some gcc-specific options, but these can be fixed later - it seemed more important to make the warnings visible to developers.
Remove JTS support from liblwpostgis; native GCJ-compiled JTS code is reported not to be reliable enough within a production environment, so well stick with GEOS.
Some more updates to lwpostgis.sql.in.c; correct a couple of missing conversions from OPAQUE_TYPE to internal (how on earth did regression tests pass with this still in place??), plus remove the UPDATE on pg_opclass to change the OID of the index storage type since we can do this by specifying a STORAGE clause instead.
Update copyrights for configure.ac (rewritten from scratch, and now renamed from the deprecated form configure.in) and also the PROJ.4 version detection macro
Switch all SQL and PL/PGSQL stored procedures over to use dollar quoting instead of apostrophes for function bodies. At last, most of the stored procedures actually become readable

Commit new PostGIS debugging infrastructure. These changes unify all the debug logging to use a new set of macros: LWDEBUG()/LWDEBUGF() for LWGEOM functions, and POSTGIS_DEBUG()/POSTGIS_DEBUGF() for PostgreSQL functions. To enable debugging, run configure with --enable-debug and then remake the entire project. If --enable-debug is omitted during configure, the above macros evaluate to (void)0, and hence should be removed by the compiler during optimisation. Also: contains minor warning cleanups and a fix for the ST_Dwithin SQL definition.
