Until recently (or maybe not too recently) ES3 extension header was
"currently empty", now the extension header is shared with ES2. It's
nice to finally get rid of all the weird ifndefs.
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.
They are now not exposed to the user at all, as their API will be
probably changed and reworked in the future to allow GLX/EGL-specific
extension to be used. Also this looks scary in the documentation.
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.
The event is called only if any button is pressed, added Button::Left
which is always present. This is just for source compatibility with
other Application implementations.
Doing it the same way as in Sdl2Application, as this doesn't have any
performance impact (just alias for already present variable).
The other way around, i.e. combining mouse buttons and keyboard
modifiers in Sdl2Application, would have unnecessary performance
penalty, as keyboard modifiers must be queried with separate function,
even if they won't probably be used at all.
Qt employs similar approach.
The old way is preserved for backwards compatibility, but marked as
deprecated and will be removed in future releases.
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).
Renamed AbstractTexture::maxSupportedLayerCount() to maxLayers(),
which is in fact alias to Shader::maxCombinedTextureImageUnits(). Also
renamed Samples::maxSupportedAnisotropy() to maxAnisotropy(). It now
has slightly confusing naming, will fix that later. Both
original functions are now alias to new ones to retain source
compatibility, will be removed in future releases.
Also printing the values in magnum-info.
Renamed AbstractShaderProgram::maxSupportedVertexAttributeCount() to
maxVertexAttributes(), the old function is now an alias to retain
source compatibility, will be removed in future release.
Also printing the values in magnum-info.
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.
In 1.8.5 it is now possible to reference directly to enum member.
Hooray! Also added explicit @ref here and there, fixing some referencing
bugs along the way.
Makes some cases less consistent (and some convenience shortcuts
impossible), but goes well with the attitude "don't use pointer when it
can't be null".
