Minimal updates (just the include guards) so Git is hopefully able to
detect the rename and track the history properly.
Everything except Magnum::GL doesn't compile now.
There will be numerous additions to this one so it made sense to make it
a static library instead of a header-only library. That also allows
CMake users to just link to Magnum::OpenGLTester instead of going
through the pain of a huge branching in order to find a correct
windowless application just to run their tests. It could have been done
even without the static library using a INTERFACE target, but that
wouldn't work on CMake < 3.0 (which, unfortunately, quite a few people
are still stuck with).
Unfortunately it's already heavily used elsewhere so I had to go through
the pain of deprecating the old implementation. The old implementation
was header-only so it can't be just typedef'd to the new one as there
would be linker failures. So the old header is just kept as it was, with
only the macros reduced.
What this changes:
* Before, a Version::GLES310 shader was created with `#version 450`
directive, which is wrong, because an implementation might support
GLES 3.1 but not GL 4.5 so this was not working and also the syntax
is a bit different so this wasn't helpful at all.
* Similarly, Context::isVersionSupported(Version::GLES310) was checking
for support of OpenGL 4.5. Now it just checks for
`ARB_ES3_1_compatibility` extension.
* Added a small isVersionES() utility that just tells whether given
version is ES or not.
103% of use cases use the returned value directly without checking, so
we might as well do the check ourselves. Added new function hasCurrent()
and added deprecated backward-compatibility conversion and -> operators.
Wow, that creeped to a lot of places.
Last dinosaur from the pointer age.
I wanted to preserve the parameter-less constructor of tests, but WINAPI
requires fairly ugly entagled set of functions, passing HWND around,
which required storing it in a global var and hoping it is properly
initialized when querying it for it to be passed to application
constructor.
When this was done, it was now fairly easy to support passing also
argv/argc to application constructor, which in the future will enable
selective disabling of extensions for even better test coverage.
This however needed slightly different main() function and thus we now
have MAGNUM_GL_TEST_MAIN() instead of CORRADE_TEST_MAIN(). Using the
latter will result in an assert inside std::optional.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
They provide the same or slightly different functionality as is present
in ES3 itself, causing confusion. Fortunately this change required only
one modification in Context test and nowhere else.
