FIXUP removed unnecessary warning

FIXUP added some comments to visit_object

FIXUP less sloppy with bool vs. int

Alembic import: prevented unnecessary vector scaling

Alembic import: moved import-time scaling to different function

convert_matrix() now only converts from Imath::M44d to float[4][4] (taking
different camera orientations into account). Import-time scaling is now
performed by the caller.

Alembic: removed unnecessary matrix copy

Alembic: simplified AbcEmptyReader::readObjectData

Alembic: added some r_ prefixes for return parameters

Add some basic UI and RNA feedback for overriden properties.

For now chose some teal blue to mark overridden state of prop in UI,
kind of last nicely different tint available...

FIXUP reinstated GHash *

Merge branch 'writefile_rework' into id_override_static

Merge branch 'master' into writefile_rework

FIXUP: float -> short in copy_yup_from_zup

FIXUP: superfluous create_empty=true

FIXUP code style

FIXUP cleaned up if-parent structure in AbcExporter::createTransformWriter

FIXUP no longer using typedef for m_shapes_type

Alembic import: replaced GHash * with std::map<>

The char* that were returned by Alembic were unstable, as they pointed to
Alembic-managed memory, which Alembic reuses for different strings. As a
result, the pointers were unsuitable for hash keys. Copying the strings
into std::string instances solves this.

Alembic: more lenient check on absence of sheer & homogeneous scaling

Checking precise values of floats is not a good idea.
