This patch introduces the initial implementation of
- A `LayerFactory` abstract class that creates `style::Layer` instances of
a certain layer type (line, hillshade, round, ..)
- A singleton `LayerManager` class, which is responsible for initializing
the `LayerFactory` instances and forwarding the `create()` calls to the
corresponding factory.
The `style::Layer` class now exposes all the properties contained at `style::LayerImpl`.
This allowed to drop `style::Layer::accept()` method usage, avoid the repeated generated code
and thus save some binary size.
This patch is a part of the layers modularization effort.
we missed a check for RenderTile.needsClipping when generating the new ClipIDs for some tiles, resulting in incorrect clipping that caused flickering in some cases
We optimize our updateRenderable algorithm by breaking ascent when we've already checked a certain tile. So far, we've compared the UnwrappedTileIDs, but they don't include the overscale component. When ascending through overscaled tile IDs, we've stopped the ascent too early, when we should've kept the search going.
Commit 1c53dc9ca8 ([core] Refactor vertex array object extension
initialization) changed where the GL renderer string is checked in order
to prevent the vertex array extension initialization in certain
platforms and in doing so made the logging of that string more frequent,
once per context initialization instead of at most once per process.
This is a lot more verbose, specially when running unit tests, so make
sure that string is logged at most once as it was previously.
when a source-expression like `["get", "property"]` evaluates to null and the default pattern value (empty string) is used, make sure attribute buffers get populated to avoid crashing the app
The ANGLE implementation of GL_KHR_debug on Direct3D seems to be broken
leading to a bad_alloc being thrown when running with a debug build, so
disable it in that platform.
Currently the vertex object extension is disabled through an ifdef for
the Windows platform due to an issue with ANGLE, while there is a
blacklist for other platforms. Unify those by adding ANGLE to that
blacklist and some small refactoring.
