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.
Currently XEglApplication and GlxApplication were requesting only ES2
context and SDL2 was not requesting anything in particular (but in
theory should work on ES-only systems flawlessly). Now explicitly
requesting ES3 if MAGNUM_TARGET_GLES3 is enabled and also explicitly
requesting ES in SDL2, so it is usable also with
MAGNUM_TARGET_DESKTOP_GLES.
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 :-)
Resolves some linker errors in Windows, removes code bloat from Platform
namespace (previously it was copied in _every_ *Application).
Originally this was in Platform namespace because I thought that it
would be possible to have one version of Magnum library for both desktop
and ES and the actual Application would determine which GL edition will
be used. Fun idea, but it would remove the static checks (e.g.
accidentaly using geometry shaders on ES), which isn't worth it.
Removed all known GLEW workarounds, added one small workaround for
missing ARB_texture_compression_bptc. I didn't want to patch glLoadGen
for just four enum values, this way it's possible to use stock one
without any patching (except for missing OpenGL 2.1 support, as stated
in external/OpenGL/GL/README.md).
As one file now replaces both `glew.h` and `glcorearb.h` and it has the
same size as `glcorearb.h` alone , it saves approximately 18k LOC,
resulting in 15 second shorter compilation time (5:03 before, 4:48 now).
Not bad.
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.
Finally something that can be used for:
* Unit tests
* Resource compilation
* Benchmarks
* ...
I also desperately need something similar for Windows (and Mac OS, too).
We still want to target old Intel machines with OpenGL 2.1. Also moved
important information from constructor documentation to class
documentation. Who would look into constructor documentation for that?
Because with NaCl WindowContext doesn't make sense anymore, the classes
are now renamed:
* Contexts namespace -> Platform
* *WindowContext -> Application
Hopefully this is (one of) last crazy renaming runs.
Magnum.h now doesn't include anything except OpenGL headers, thus
changes in Math library don't trigger recompilation of everything, but
only of things really depending on it.
Math constants moved to separate file for similar reasons, de-inlined
some functions to remove the need for some #includes.
