(core): write a section dedicated to matrix naming and notation
Description
There is no strict naming convention for matrices and it is often done terribly.
Having such a convention would help us to better understand linear algebra thereby making reviews a lot easier.
Proposal
The notation should be similar to what was already described in this document.
Transform matrices should mention their source and destination spaces in their name. Perhaps like this:
m_destination_source
(or matrixDestinationSource
)
Writing the source at the end is helpful for matrix multiplication.
e.g.: m_a_b * m_b_c = m_a_c
