directory is used.
This is done by appending the name of the file as extra folder. Existing
projects may need to regenerate their proxies but it should be possible
now to have all proxies nicely in the same custom folder.
Next commits will include operators to copy directory settings between
selected strips, making the process faster.
off.
GPUs need a full tree of mipmaps up to dimension 1xn to work. This will
make it so for all imbufs but cost is negligible and it's unlikely that
something could break due to that.
This patch makes it possible for the user to select all supported compression types in OpenEXR 2.2
Discussion points:
- B44 is only defined for half's it compresses to a fixed representation of 44% of the halfs. We do currently not reflect in the UI that in the case of float32's it will be equal to compression = NONE
- ZIPS is single scanline zip and is supposed to be useful in cases where importing in Nuke happens.
- The new Dreamworks formats, are the worth exposing etc etc

If user cancels, there's an issue with leftover files.
Instead use a hash to record files that have akready been registered for
generation and skip them if so.
That should guarantee things will go smoothly and when a file exists it
is assumed to be valid.
Height of bitmap may be negative, which indicates a 'top to bottom' line storage.
Also, fixed header handling, bitmaps using other header than 'BM' would most likely
have lead to errors/crashes too...
This is a per-strip option next to the build proxy size which tells blender
whether to skip building proxy size if the file for it already exists or not.
The option is called "Overwrite" for simplicity.
This option is enabled by default to avoid changes in the file behavior.
TODO: Would be nice to do something like that for movie clips as well.
Murmur2a is a very fast hashing function generation int32 hashes.
It also features a very good distribution of generated hashes.
However, it is not endianness-agnostic, meaning it will usually generate
different hashes for a same key on big- and little-endian architectures.
Consequently, **it shall not be used to generate persistent hashes**
(never store them in .blend file e.g.).
This implementation supports incremental hashing, and is a direct
adaptation of reference implementation (in c++):
https://smhasher.googlecode.com/svn-history/r130/trunk/MurmurHash2.cpp
That cpp code was also used to generate reference values in gtests file.

trash with float images.
Issue is uninitialized alpha in the clone brush + a clamping issue for
float images. There's still some 'swimming' and brightness issue here
but I have to do work for the weekly, will investigate further later.
