Bborie Park e20f3d0a60 Refactored rt_band_get_min_value() to call new function rt_pixtype_get_min_value(). Addition of function rt_util_extent_type().

Bborie Park 4c7dbc99ce Corrected rt_raster_same_alignment() and RASTER_sameAlignment() to behave as an end-user would expect it to. So intead of errors when parameters don't match, return false.

Bborie Park 8864196bef Changed rt_raster_has_no_band to use 0-based band index instead of 1-based. Removed function prototype ST_HasNoData(raster) as the other prototype ST_HasNoData(raster, nband) now uses the default value of 1 for nband.

Bborie Park b9ab21eabb Changed those functions that is 1-based for band index to 0-based in rt_core. This leaves only rt_raster_has_no_band, which may have other issues as well.

Bborie Park a3abb76533 As per Bryce's comments in ticket #1174, reduce the number of calculations when doing rt_raster_geopoint_to_cell by using an inverse geotransform matrix. Unlike the patch attached to the ticket, this commit does not change the structure of the rt_raster struct. It may be worth changing the rt_raster struct eventually, but will cost us the single memcpy when serializing rt_raster. Also, changes for testing SRID as "unknown" if value is lte SRID_UNKNOWN (presently 0). 
Associated ticket is #1174.

Bborie Park 295c02be84 Changed adjustment of extent by half-pixel to full-pixel for points and linestrings to ensure compatibility with GDAL 1.6, 1.7 and 1.8. GDAL 1.9 (current trunk) appears to work fine with half-pixel adjustments.

Bborie Park 56791ce3b5 Fixed the problem where having configure detect that GDAL has the GDALFPolygonize function does not cause the code to use GDALFPolygonize. This is due to the macro GDALFPOLYGONIZE not being set anywhere. So, it is now being set in raster_config.h.in and included in rt_core/rt_api.h. Had to update testapi.c as the geometries generated differ depending on whether or not GDALFPolygonize is used.

The regression failure in ticket #1064 should be resolved as a side-affect of the new function as the srtext returned through SPI is copied to an interval variable.

Bborie Park 6ebb8e7534 Addition of rt_raster_gdal_warp function in rt_api.c. This was written based upon GDAL's gdalwarp utility to provide a flexible means to reproject, change the scale of, adjust the skew (deskew) of and shift the origin of a raster. RASTER_transform in rt_pg.c has been adjusted to make use of rt_raster_gdal_warp instead of rt_raster_transform. Regression te 
sts confirm that resulting rasters from rt_raster_gdal_warp are identical to that of rt_raster_transform.

The abilities to change a raster's scale, skew and origin have yet to be tested and have no user-accessible SQL functions as of this revision.  This will occur in future revisions.

The function rt_raster_transform will be removed in a future revision.

Bborie Park 60c2a10862 Added support for coverage tables to ST_Histogram. This entailed adding the ability to explicitly specify the min and max values in the underlying C function rt_band_get_histogram. The min and max parameters should ONLY be used by the established coverage table handling ST_Histogram functions as the returned percent element of the histogram type is changed from returning the percentage to returning the sum of counts for that histogram.

Bborie Park 4752433c0d Add ST_Transform function that achieves the primary purpose of reprojecting a raster to a new projection system. This makes use of the GDAL Warp API function GDALAutoCreateWarpedVRT(). In the future, the underlying C function is expected to be refactored to support skewing and pixel scaling at the same time the raster is reprojected. 
Really minor changes to rt_pg/rt_pg.c adding initilization values to variables for eliminating compile warnings in Windows (thanks Pierre).

Jorge Arévalo 6f16c2bfcb Changes in raster memory management: 
- Only calling function memory context is used, except in SRF functions, where
multi_call_memory_ctx is used.
- rt_context internals hidden. The memory management and error reporting is
performed by rtalloc/rterror family functions. They simply call rt_context
struct fields as requested. Same philosophy here than in liblwgeom.
- Now rt_context memory is statically allocated. Before this, new memory for
rt_context was allocated in every function call. And the memory was allocated
outside the calling function (in fcinfo->flinfo->fn_mcxt postgres memory
        context).
