Details:

Setting non-valid values for some properties leads to un-expected results
(e.g. bug #49755: axis equal clears plot). These should instead throw an error
(as they do in Matlab).

Attached is a work in progress patch that adds new constraints (finite_type)
for array_properties, row_vector_properties and double_properties. It also
expands the support of min-max-constraints that we already have for
double_properties to array_properties and row_vector_properties.
I added these constraints to some of the properties to which they apply.
However, I would like to know whether this is the correct approach before I
continue.

I am adding Pantxo to the CC list since this is very similar to what he did in
task #11311. Pantxo, could you please comment when you have the time?

I also changed "plotboxaspectratio" and "dataaspectratio" from
array_properties to row_vector_properties since this is how they are handled
in Matlab. Should this change be made in a separate bug report?
