This definition was used to control the accessibility of some class members, changing protected qualifiers to public. This introduced unnecessary coupling between components and headers.
All conditional access specifiers have been set to public, which should not be a problem given the low number of classes that actually used affected members. Another albeit more complex solution could have been to use friend classes.
* Use std::max and std::min, with an initializer_list where possilbe.
* Use std::clamp where appropriate.
* Missed a couple of them.
* Remove clamp specializations at @Lgt2x suggestion.
This is all in unused/unnecessary/leftover code, but the code wouldn't
build without Xlib headers on the system, which was forcing the Mac builds
to install xquartz.
This also removes renderer/SoftwareOpenGL*, which was _not_ a
software-rendered OpenGL, but just an older version of the same code that's
in HardwareOpenGL.cpp--old enough to still talk to glX directly, which is
what caught my attention.
The vast majority of this is fixing up `char *` that should be `const char *`
but a handful of other fixes, like potential buffer overflows that GCC
noticed, etc, were applied as well.
This removes `-Wno-write-strings` from CMakeLists.txt, as it is no longer
necessary, as there is no longer a flood of compiler warning spam when
building.
This does not fix all compiler warnings; there are still a handful, and they
are legitimate, but they can be dealt with in a future commit.
