Port of https://github.com/mapbox/mapbox-gl-js/pull/5101: adds a new render pass `Pass3D` before any other rendering wherein we render layers with 3D passes (fill-extrusion layers) to offscreen framebuffers, sharing a depth renderbuffer between those layers in order to render 3D space correctly. Those framebuffers are saved on the RenderLayers and copied back to the map during the translucent pass. Rendering to offscreen framebuffers before we do any clear + draw means we can avoid expensive framebuffer restores.
Previously, when we started a worker operation that eventually throws an exception (e.g. due to the tile not being parseable), and then enqueue another worker operation while the first one is processing, we treated the worker as idle once the first operation's error callback fired, even though the second operation was still in progress. Due to our use of coalescing, I was unable to come up with a reliable test since we'd need to reproduce the behavior described above, which is timing dependent.
Since 9a9408e811, we marked tiles as non-renderable if an error occured. This lead to situations where a tile was loaded + parsed successfully, then a revalidation attempt occured (e.g. because the resource was stale) which failed. In this case, we used to mark the tile as non-renderable although we could've used the perfectly parsed (stale) resource.
When a texture is deleted, it is as if all texture units to which that texture object is bound are rebound to texture object zero. Therefore it's the *bindings* that need to be dirtied, not the active texture unit.
- AnnotationData.updateData() was not completely thread safe. Calling it from the renderer thread instead of the main thread fixes this
- Since we moved the coalescing of updates out of the map and into the renderer frontend implementations, the updateData was called too much, resulting in degraded performance. Moving it into the renderer makes sure it gets coalesced again.
Ports fix for GL JS issue #5112.
Line label projection can't be based on tile geometry that's behind the plane of the camera.
The relevant tests are still ignored because the overzoomed collision behavior is different between native and JS.
