Project the extrusion and compare it's projected pixel length with the
actual pixel length and adjust antialiasing accordingly.
The previous approach calculated the adjustment much more indirectly and
had no intuitive explanation.

`altitude` was a terribly-named variable that was used to indirectly
control the fov. This should eliminate some confusion.
`altitude` was equivalent to `cameraToCenterDistance / height`

This replaces a hardcoded shader approximation with a more correct,
FOV-dependent one.
`gl_Position.w - 0.5`
is replaced with
`gl_Position.w / tan(fov)`
The `/ tan(fov)` is handled by multiplying `1 / tan(fov)` into `u_gamma`
outside the shader.
I think `- 0.5` was just chosen as something that looked right for the
default fov.lease enter the commit message for your changes. Lines starting
* [core] Add interface to get image from sprite atlas
* [tests] Add tests for Map::getImage
* [ios, macos] WIP: get MGLImage for name from style
* [ios, macos] Fixed -imageForName:
Convert from sprite images to platform images using the existing encodePNG() function, which is also used for printing. Allow -imageForName: to return nil without an assertion failure. Added a basic test.
- Trim whitespace from labels before determining their max-width for alignment.
- Fix crash on labels that contain lines with only a single character of whitespace.
std::to_string() potentially uses a decimal point character different
than a dot (.), depending on the environment's locale. But since this
generated string will be part of GLSL code, there needs to be a dot and
nothing else.
Added new layers and sources properties to MGLStyle that contain all the style’s layers and sources, respectively. These properties are KVC-compliant with all the mutable to-many methods. Layers are ordered from topmost to bottommost, for consistency with Cocoa APIs where front/first means top and back/last means bottom.
Also added storage for mbgl::style::Source in MGLSource proper for wrapping AnnotationSource. Until the style finishes loading, its name property is set to nil.
Fixes#6003.
This converts the style property classes (CirclePaintProperties and so on) to the same tuple-based approach as gl::Attribute and gl::Uniform. The approach is outlined in https://github.com/mapbox/cpp/blob/master/C%2B%2B%20Structural%20Metaprogramming.md.
The main advantage of this approach is it allows writing algorithms that work on sets of style properties, without resorting to code generation or manually repetitive code. This lets us iterate on approaches to data-driven properties more easily.
Another advantage is that the cascading, unevaluated, and evaluated states of a set of properties exist as independent structures, instead of individual properties holding their own state. This is a more functional approach that makes data flow clearer and reduces state.
