Add working color space as input parameter in Sampling, Calibration and Merging HDR nodes. (unused in calibration, but useful to transfer from sampling to merging in pipelines)
Update rawColorInterpretation default value and add some comments in cameraInit.
Regular expressions in regular strings generate deprecation warnings
with Python 3 ("invalid escape sequence \x"). To fix these warnings,
the regex must be contained within a raw string. For nodes that have
parameters whose description and/or value contain regex, the strings
are transformed into raw strings. In the case of descriptions, which are
generally written across several lines, regular strings are concatenated
with regular strings to preserve line returns (with "\n", which becomes
uneffective in raw strings).
In particular:
- In common/, remove the backport of weakref.WeakMethod
- In docs/ and ui/, use the standard FileNotFoundError class
- Use built-in open() instead of io.open(), and stop importing io
- In core/stats.py, use the standard implementation of xml.etree instead
of the C one
Fix the parameters with default values that do not correspond to
the parameters' types. For CameraInit, all the default values of
FloatParams that are set with integers are replaced with actual
float values.
These default values with an erroneous type would cause changes
in the CameraInit's UID when the intrinsics' default values were
written (with values of the correct type) and when they were
loaded (with values of the wrong type).
InitNode is an abstract class which is meant to be inherited
by all the initialization nodes (such as CameraInit), included
those that might be created by the user.
InitNode contains methods that can be reimplemented by the
children classes if necessary.
This abstract class allows to keep on using scripts such as
meshroom_batch without having to modify them specifically or
being limited to using a CameraInit node.
Set the value of the string parameters in the nodes' description as
the unevaluated variable instead of the evaluated variable. The
evaluation will be made later, when the nodes with such parameters
will be computed.
