Port stdlib to python 3 / Qt5

Hello, I wanted to use the point_selection function from the original release of MARS in OpenAlea.

This function can be imported from openalea-components:
from openalea.image.gui.point_selection import point_selection

However I cannot make it work, using either ipython, ipython --gui=qt nor python... I always get the following error message:

QWidget: Must construct a QApplication before a QPaintDevice
Abandon (core dumped)

Could someone help/tell me what could be done to try and solve this?
Thanks, Jo

The following remarks come from the use of the demo node display which displays an image using slide_viewer class:

• got Process finished with exit code 139 (interrupted by signal 11: SIGSEGV) if the image size is too big. Reproducible, for example with the following image if we reduce the size by 50% it passes, by 75% it does not
  .
• the image is displayed in the wrong direction like mirror reflection.
• the "mouse_press" is not well managed, see for instance def mousePressEvent (self, event) : in class ScalableLabel

It is time to move to conda-forge.
First, export all the Python packages.
Then, export C/C++ libraries when all there dependencies are built.

Split the package and merge the packages as submodules

This package implement the central data structure SpatialImage.
It has to be independant with a separate documentation.

Nodes drag and drop on workspace leads to ModuleNotFoundError: No module named 'image_wralea'

This is not raised for all nodes, only for the following sub-packages:

• serial, interpolation, registration

Several dependencies already exist to vplants.tissue_analysis.
Even if these deps are imported at run-time, the code is not fully functional today.
Several options exist to remove these dependencies:

1. Inherit of the data structure in vplants.tissue_analysis and add the algos in the inherited class
2. Seprarte the datastructure from the algos and use a service as a factory (I want to build my data-structure from images. This kind of solution is used in NetworkX for instance.

To be in all sub-packages
