bump dev release number
OpenEXR: Fixed issue where a stringvec of 16 items is mishandled as a maxtrix
fmath.h: Move all the "using" outside the OIIO namespace.

If the 'using' is inside the namespace block, it's basically useless
to apps that include fmath.  This mainly affects functions that fmath.h
supplies because they are missing from certain MSVS versions.
Bug fix: oiiotool color conversion botched inputs with MIP levels.

It should have been looping over the number of subimages and mip levels
in the destination image, not the source image, because if the -a flag
is not used, the dst image will be constructed with fewer mip levels
(i.e. 1) than the source. Looping over the source's count will run off
the end of the list.
Python: implement ImageBuf.get_pixels()
Switch filter API to use string_view
Fix oiiotool output of negative-origin images for formats that don't support it
TIFF: gracefully handle negative origin without asserting in libtiff
Change extract_from_list_string to return the number of values parsed.
IBA warp & rotate, oiiotool --warp --rotate

Warp transforms (with good filtering) an image by a 3x3 transformation
matrix (affine transformations and then some).

Rotate is the special case of arbitrary image rotation.
Slightly more FP tolerance in some tests
rebuild PDF docs
CHANGES update
Bump version after dev release
Move platform macros from sysutil.h to platform.h
Add OIIO_FORCEINLINE definition
Simplify includes
Refactor IBA -- break up unwieldy imagebufalgo.cpp.
Move all high-quality filtered transformations/warps to imagebufalgo_xform.cpp.
Move all drawing and visible annotation to imagebufalgo_draw.cpp.

No actual code or functionality has changed, just moving things from file
to file for better organization and faster recompilation.
Make certain IB constructors explicit.
ustring: add comparisons between ustrings versus char* and string_view.
This fixes some potential ambiguities in method selection.
Replace stray usage of boost::filesystem::last_write_time with OIIO::Filesystem
