Add a "SfM: Define Initial Pair" sub-menu in the Image Gallery menu that is
only enabled if the currently active group contains a StructureFromMotion
node. Clicking "A" or "B" will automatically set the selected image's view
ID as a part of the initial pair.
As we rely on the thumbnails cache, the images are already downscaled at
a small resolution. So there is no more need to force a max resolution
on the Qml Image.
Some QML properties access exposed Python objects that may or may not
be null upon their access. When these objects are accessed while null,
QML issues "TypeError" warnings. These warnings have no functional
impact as QML correctly handles trying to access null objects, but can
spam the logs.
This commit aims at fixing all these warnings by checking that the
Python objects are not null before being accessed.
