Old deprecations [note: macOS Makefile randomly fails in this PR]

[artificiel]

closes #1550 expect for:

bool ofDirectory::getShowHidden() can we give this a better name please?

(not exactly a deprecation) and

setCoordHandedness actually does nothing in the cpp file

not sure what is the role of that function and if it can simply be removed

pretty sure we need ofConstants included before glm, due to us defining GLM_FORCE_CTOR_INIT

[artificiel]

ahh updated in a commit. but that kind of include order dependency is inherently brittle..

i see there is also a pattern of doing #define GLM_FORCE_CTOR_INIT like e.g.

openFrameworks/libs/openFrameworks/math/ofQuaternion.cpp

Line 6 in ef6df30

#define GLM_FORCE_CTOR_INIT

but that won't help for instance if a library that uses GLM manages to get included before ofConstants...

how about setting GLM_FORCE_CTOR_INIT with a compile -D?

[ofTheo]

Agree we need to do GLM_FORCE_CTOR_INIT in all the project files. But that will be a separate PR and will take a bit of time, so need the above change to be reverted to merge :)

curious which part of this is addressing: "macOS Makefile randomly fails"

[artificiel]

ah sorry for the ambiguity! it means the tests for this PR here are randomly failing in macOS Makefiles. the last run in a Network test, the previous one in a NodeRegression Test. I cannot reproduce the failures, and the tests are otherwise all passing in other platforms.
