I wanted to add this for GlfwApplication, only to realize the timer there
is a double, in seconds, so accepting *integral* milliseconds there felt
very weird. Let's use the fancy new time types instead.
Also updated the docs to (hopefully) clarify that setSwapInterval() has
to be called in order for the interaction between the two to work
properly.
As usual, the old variant taking untyped milliseconds is a deprecated
alias to this one.
In short this means the users no longer need to care about FindSDL2 etc.,
it'll just get done automatically. They don't need to drag along
FindMagnum / FindCorrade anymore either, but having them gives a much
more reasonable error message if the library cannot be located at all, so
I still recommend having them.
Sometimes it's desirable to just make a mesh indexed unconditionally,
which wasn't really possible with this thing, and having to special-case
that at the call site is very annoying. Now it makes a mesh
trivially indexed if it has any other primitive than the ones listed,
and if it's already indexed, it's just passed through.
Following the spirit of extension-based functionality, the entrypoints
are available always but do something (i.e., call the actual WebGL API)
only if the extension is advertised. Which it is only on Emscripten
3.1.66+ because older versions don't have the corresponding entrypoints,
so there it's marked as disabled.
Additionally, EXT_polygon_offset_clamp is now also working on 3.1.66+,
but there's no wrapper for it yet.
Like with TextureTools::DistanceField, to make room for non-GL
implementations. Old names are deprecated aliases, same for headers. The
only remaining bit in the Text library is the Renderer class, but for
that one I first need to invent a non-shitty API so I can just deprecate
the old thing as a whole and create something reasonable from scratch in
RendererGL.
Along with the bits in Text library this is one of the last things that
still assume OpenGL present by default.
As usual, the old name and header is now a deprecated typedef.
The internal GL texture format (especially the R8 vs Luminance mess on
ES2) is now considered an implementation detail and shouldn't affect
common use in any way.
The format is now required always, in order to prepare for use cases
where colored glyphs are a thing as well. Additionally, to match the
recent change in AbstractGlyphCache, the processed format is specified
separately, allowing the input and processed formats to be decoupled.
Which ultimately fixes the regression on ES2 and WebGL 1 where it was no
longer possible to call font.fillyGlyphCache() on a
DistanceFieldGlyphCache.
Also, as there's now a generic format on input, another ES2-specific
issue is now fixed as well, in particular a case where a GL error
would be emitted on drivers with EXT_texture_storage because an unsized
format is passed to setStorage(). This was a problem since a long time
ago, but I ignored it because it didn't affect WebGL 1 and all drivers
that exposed EXT_texture_storage exposed EXT_texture_rg, effectively
circumventing this issue. Or so I think, at least.
The constructors taking either a GL::TextureFormat or no format at all
are now deprecated aliases to the new functionality.
The refactor in 6707534ce6 somehow didn't
account for the need to have a different pixel format for the input and
the processed texture, which is needed on ES2 / WebGL 1 because there's
no renderable single-channel format. Which means distance field text
rendering was broken since then.
This commit is the first part of fixing that regression. It makes the
AbstractGlyphCache aware of the processing being done, decoupling the
input and processed format and size. Which also allows the base
implementation to provide interfaces that so far were only limited to
DistanceFieldGlyphCache, thus eventually making it possible for font
plugins to supply a pregenerated distance field image through
fillGlyphCache() and not just through createGlyphCache().
The two DistanceFieldGlyphCache APIs that are now directly on the
AbstractGlyphCache are now deprecated aliases to the new functionality.
The actual fix for the ES2 / WebGL 1 regression will come in the next
commit, as it's pretty much a separate step that involves updating the
GlyphCache as well.
Doxygen 1.12 has no longer a completely insane matcher and discards
those as it should. With 1.8.17 classes had to be referenced with
Corrade:: but functions, typedefs and variables didn't need to be and it
was a complete utter chaos.
Same as done for Containers::StaticArray some time ago. Since it's not a
potentially dangerous operation, it's not made as an overload of the
from() function, but instead a regular constructor. It's however kept
explicit for now, even though it eventually might not need to be -- I'm
not sure about potential consequences yet.
Based on the actual text direction (either explicitly set or detected),
these resolve to either *Left or *Right. For the Text::Renderer it's
done automatically inside (and there's no way to actually set the
direction from outside due to the API being ancient and limited), for
the align*() utils the alignment has to be explicitly resolved using a
new alignmentForDirection() utility.
This all looked obviously correct so I never questioned it, but the spec
itself has the order mixed up for an unexplainable reason so it doesn't
match between MouseEvent and MouseMoveEvent.
This is what both SDL and GLFW do, so it makes sense to be consistent.
Without it it's also impossible to handle keyboard shortcuts such as
Ctrl-C when editing text, which is rather silly.
Originally (2012? 2013?) I expected that there would eventually be
OpenGL ES 4.0, thus it made sense to differentiate between ES2, ES3 and
something else ES yet unknown. But as ES4 was increasingly unlikely to
happen, the internal code treated MAGNUM_TARGET_GLES3 as a simple
inverse of MAGNUM_TARGET_GLES2, and only in a very few places,
only adding confusion.
Thus it's now deprecated and defined as a simple inverse of
MAGNUM_TARGET_GLES2 on MAGNUM_TARGET_GLES builds, and none of the
internal code uses it anymore.
Like the Deg / Rad classes, these are for strongly-typed representation
of time. Because the current way, either with untyped and imprecise
Float, or the insanely-hard-to-use and bloated std::chrono::nanoseconds,
was just too crappy.
This is just the types alone, corresponding typedefs in the root
namespace, and conversion from std::chrono. Using these in the Animation
library, in Timeline, in DebugTools::FrameProfiler, GL::TimeQuery etc.,
will eventually and gradually follow.
Breaking change, but the new behavior makes a lot more sense. Hopefully
not that significant breakage -- I don't assume people regularly worked
with angles this way.
Whoops, this got silently omitted during the massive refactor in
f7a6d79aa0 (Nov 23). Buffers *do* get
destroyed, VAOs not. If you got sudden GPU memory usage issues after a
recent Magnum update, this was why.
This "type erased std::vector member" was done in the times before
growable arrays were a thing, and kind of made sense to go the extra way
to avoid a <vector> include in the header. Except that it made rather
unportable assumptions about std::vector size, which weren't correct for
example with _GLIBXX_ASSERTIONS set.
But what was *completely* unacceptable was that the vector was of one or
another type depending on the GL feature set present in the current
context. Apart from adding a lot of extra *nasty* logic to construction,
moves and destruction, this approach led to the mesh instance asking the
current context on destruction in order to know whether a destructor
should be called on std::vector<Buffer> or std::vector<AttributeLayout>.
Ugh.
Now it's a regular Array member (which isn't *that* heavy to need such
type-erased treatment, although it eventually could be), and thanks to
the AttributeLayout packing improvements in previous commits it's no
longer prohibitively wasteful to just abuse AttributeLayout instances to
store just owning Buffer instances alone -- doing so now wastes only 16
bytes per buffer, compared to 36 before. Given there's usually just one
or two vertex buffers per mesh (compared to attributes, which are
usually 4 or more), it should be fine.
The MeshGLTest::destructMovedOutInstance() test added few commits back
also no longer asserts on no GL context being present.
Want to construct them without a GL context present, and Optional is too
wasteful. Also adding it to the AbstractGlyphCache base, where it skips
also allocating the internal PIMPL state, because it's not going to get
used for anything in a NoCreate'd instance anyway.
The test added in previous commit now passes. Besides the behavior being
different for single- and multi-bind calls, an additional "interesting"
behavior is that the glBindBufferBase() / glBindBufferRange()
apparently also creates the GL object, if not already (in contrast to
the multi-bind APIs which *require* the GL objects to be created
before).
