Sorry that it took ages. Oh, actually, I'm not able to test this AT ALL
because my awesomely amazing NVidia Optimus laptop CANNOT (what?!) do
VSync because of some bad design decisions from previous century that
led to the disaster that we now know as X11 and as I heard it is
impossible to work around that or something. Ugh.
Originally enabled just on OSX, apparently something similar is needed
also in Mesa. If the version is not user-specified, core GL 3.2 is
created on OSX, core 3.0 elsewhere. If that fails, the application falls
back to creating compatibility 2.1 context.
Hopefully I didn't break anything. The only difference on OSX is that
the application doesn't fall back anymore if the version is
user-specified.
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.
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.
Before this commit the default context creation in tryCreateContext
would create the OpenGL 2.1 context.After this commit by default,
the OpenGL 3.2 context is created by default, if this fails
tryCreateContext will fall back to creating a OpenGL 2.1 context.
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.
Emscripten supports some hybrid between SDL1 and SDL2. I don't want to
add Sdl1Application just for that and create more portability issues, so
I just changed some things in Sdl2Application to be compatible with what
Emscripten wants. Full SDL2 support is awaited in Emscripten, thus this
is future-proof (rather than having SDL1 support, which would be
deprecated later).
Added documentation about Emscripten usage and template HTML markup to
Sdl2Application docs, will move it somewhere else in the future when
more than one Application will be supported (e.g. GLUT).
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.
* Explicitly set multisample attributes in all cases (so the attributes
are always properly set when creating another context).
* Do both assign and test in `if` statement.
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.
