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.
In NaCl the wheel event is something completely different than mouse
event and in my opinion overly complicated (the scrolled distance is
measured in pixel precision!).
To preserve at least some compatibility with other toolkits, the events
are shoved into normal MouseEvent. Sadly the event doesn't contain any
position information.
Don't do anything to respond to viewport size by default, as the window
has fixed size in most cases anyway (always fullscreen, canvas of fixed
size in browser etc.). Makes the initial implementation requirements
much simpler and shorter.
Somebody would just want to defer context creation after parsing
arguments or doing some validations without any particular setup, thus
having to write even the {} is annoying.
Added missing tryCreateContext() implementations. Error messages are
printed only by tryCreateContext(), createContext() is only a thin
wrapper which exits the application if tryCreateContext() fails and
doesn't print any additional information on the output.
Hopefully I didn't break anything :-)
Better API for handling more than one application screens (context
switching, event propagation etc.). Taken from Push The Box, updated to
current coding style and templated.
In addition to 37e4f9d6f7 which did the
change for Sdl2Application (because Emscripten required it), making sure
that everything (except GLUT, which does it by default) behaves the
same.
Moreover, some applications don't expect viewport size changes at all
(e.g. the app can't change size of immutable texture used for rendering)
and thus the original way to defer the initialization until
viewportEvent() is called would be overly complicated.
Also, since framebuffer classes store viewport size in them, there is no
need to call viewportEvent() on initialization. The current ways to do
the initial call in Sdl2Application, *XApplication and NaClApplication
were nothing more than ugly workarounds for mimicking GLUT behavior,
which is bad.
Lastly, to be sure that nothing breaks in user apps, I did this change
in magnum-bootstrap long ago and all bootstrap application behave the
right way.
Each implementation of *Application::Configuration will have different
methods tailored to feature set of the underlying toolkit. Currently
each windowed application's Configuration has only window title (except
NaClApplication) and window size. WindowlessGlxApplication has empty
class. More features will come later. Also created introductionary
documentation for Platform namespace.
Apparently input events can be processed during buffer swapping. Now
asserting that callback from buffer swap is not called during input
event processing (which shouldn't, as both functions should be called in
the same thread).
NaCl and SDL2 are now hotswappable again without any unimplemented or
superfluous function parameters.
Also added missing EnumSet operators for Modifiers.
