* Add globe view projection

- Extend symbol data structures to support reprojection
- Use more explicit "tileAnchor" naming for anchor fields in data
structures.
- Extend symbol data structures to support 3D anchor points in preparation of data reprojection model required for the globe view
- Update shaders to support variable directions for elevation
- Add helper functions to the Aabb class
- Add z-component support to symbol shaders
- Globe view refactoring
- abstraction work
- working on symbol reprojection abstraction
- symbol projection abstraction
- Separation of globe atmosphere effect
- Fix atmosphere render on retina display
- Force reload of symbol layers on projection mode changes
- Fix pitched symbols on globe
- Prevent expensive call to buffer updates and use shared tile vertex buffers (#10944)
- Updating buffers flagged with GL_DYNAMIC_DRAW was an expensive part of the frame
with roughly half of the frame time spent updating buffer data. To prevent that
initialize the shared data once and store the tile buffer data per tile instead
- Separate pixelsPerMeter to standalone uniform (#10967)
- Separate pixelsPerMeter to standalone uniform
- Add separate getter for normal up vectors in tile transform
- Code review fixes
- Change tileSpaceUpVector to tileSpaceUpVectorScale
- Add up vector scaling to collision and symbol drawing (#10987)
- Fix occlusion of map aligned line labels
- Globe view to mercator transition for sphere geometry (#10984)
- Interpolate between mercator and globe view
- Interpolate on the GPU
- Interpolate the zoom transition in the shader
- Simplify readability of shader code
- Switch projection after transition
- Reenable static buffer optimization and use triangle face culling
- Apply correct transforms to globe raster depth shader
- Update projection during render loop
- Reintroduce tile globe matrix
- Revert globe tile vertex size
- Cleanup vertex layouts
- Cleanup shader code and share functions in prelude
- Update transition switch range
- Fix pole rendering
- Add globe to mercator transition for symbols
- Add shader variant PROJECTION_GLOBE_VIEW
- Address FIXME, prevent projecting points using stale layout attribute data
Since projections may create a dependency with the symbol layout buffers
as we store projected points in it, we need to prevent rendering of such buffers
when switching projections
- Revert vertex grid size change
- Fix missing attribute in symbol_text_and_icon.vertex.glsl and apply
transition changes to all symbol and icon shaders
- Apply transition fade for viewport aligned labels
- Prevent line label interpolation during the transition
- Add support for terrain during the transition and fix up vector transform
- Fix up vector transform along longitudes as up vectors are shared between
all tiles along longitude, they need to be rotated correctly based on their
tile y id
- Keep zoom constant to compensate camera altitude properly and account
for projection scaler in globeMercator matrix and z extrusion
- Account for projection scaling in symbol inversion matrix
- Apply review changes from #11015
- Simplify zScale calculation in globe mercator matrix
- Dead code removal and remove unused
- Remove usage of pointCoordinateOnGlobe, make it part of the projection interface

- Remove unused anchorIsInside function calls
- Fix collision circle placement
Fix ~30 mercator render tests
- Fix variable anchor elevation
Fix ~32 mercator render tests
- Fix mercator matrix
Fix custom layer render test
- Reset globeGridBuffer and globePoleBuffer to prevent corrupt access
- Fix symbol anchors with terrain
- Remove unused u_label_space_scale uniform
- Remove unused parameter
- Remove unused variables
- Green CI and miscellaneous fixes (#11193)
- Fix inverted frustum matrix on non-globe projection
Fixes camera-fit and free-camera render tests
Skip last failing test render-tests/fill-extrusion-pattern/opacity-terrain
- Fix linter
- Fix build
- Fix flow
- Consolidate atmosphere buffers in shared globe buffer struct
- Fix data/symbol_bucket.test tests
- Fix util/primitives.test
- Fix ui/camera.test
- Add FIXME for transform unit tests
- Fix symbol/cross_tile_symbol_index
- Fix linter
- Address review comments
- Add unit test FIXME ui/camera.test
- Fix some matrix precision change to fix flow and keep precision
- Replace tile backface culling by far plane adjustment for frustum culling (#11214)
- Add ray closest point on sphere
- Add common projection interface farthestPixelDistance
- Add PROJECTION_GLOBE_VIEW define when globe rendering is enabled
This allows enabling the elevationVector function and fixes rendering
of terrain with globe view
- Add wireframe mode + reduce vertex resolution (#11237)
- Use GLOBE_VERTEX_GRID_SIZE = 64 and consolidate vertex buffer functions in GlobeSharedBuffers struct
This uses the same vertex grid size as gl-native, refer:
mapbox/mapbox-gl-native-internal#2348
- Add support for globe wireframe mode
- Remove GlobeTile class, inline function call
- Remove unused
- Remove globe specific code path
- Address FIXME unit test ui/camera.test
Reduce and consolidate redundant code
Remove globe specific code path from gesture interaction
- Consolidate globe specific code
