That was unprofessional from me, sorry, because it didn't even compile.
When I got it to compile, it crashed right away, because I was querying
GLX function instead of WGL function. But even after that it was still
crashing BECAUSE APPARENTLY YOU HAVE TO CREATE CONTEXT TO BE ABLE TO
CREATE CONTEXT, YO DAWG.
Fuck all this GL shit. Gimme something sane already. Ugh.
Binary AMD drivers require the user to explicitly request the debug
context on context initialization, otherwise all debug functions are
no-op. This allows us to use debug functionality in command-line utils
and, mainly, GL functionality tests.
The Windows versions are coded without testing, so I hope I did not break
something :)
The parameterless Platform::Context::Context() constructor and
Platform::Context::tryCreate() function are deprecated in favor
functions that take argc/argv pair. The Context class now accepts
arguments starting with --magnum-* prefix. Currently there are none
except for the implicit --magnum-help, but that will change with the
following commits.
In some cases the GL context creation might success without error, but
the created version is one that we don't want (e.g. software GDI
rasterizer on Windows). Previously the Context class constructor just
exited the application and it was impossible to react on that from the
application side (for example reducing some context feature
requirements).
Now there is Platform::Context::tryCreate(), which returns either
created instance or `nullptr` if the instance creation failed with some
error. That is now used in all Platform::*Application implementations.
