points2grid release notes

Version 1.0.2: 

Version 1.0.2 of Points2Grid is a minor release, adding several small
features to the prior 1.0.1 release. These include:

* A compile-time option to align grids to the origin (0,0): Grids can now
be aligned to origin, or to the lower-left corner of the dataset as in
previous releases.

* A compile-time option to set an upper-bound on grid size: Out-of-core
operations have the possibility of exhausting all available disk space
and crashing, with sufficiently high resolutions and large datasets. A
suitable upper-limit on the number of grid points allowed in output can
provide protection from this. With this option enabled, when the
calculated grid size exceeds the pre-determined limit, Points2Grid will
abort.

* Support for libLAS 1.7+: Support for libLAS 1.7+, using the libLAS C
API, has been back-ported from the CRREL fork of Points2Grid. Support for
libLAS 1.2.1 and earlier through the native C++ API continues to be
available as a compile-time option.

Version 1.0.1:

Version 1.0.1 of Points2Grid is a minor release, adding to the prior 1.0 release. 
Through the 1.0.1 release, Points2Grid is now available under an updated 4-clause BSD 
license.

  null values
