Get glyph metrics from the font in the process of drawing each glyph into a bitmap context. These metrics result in more accurate kerning and better aligned baselines than the previous hard-coded values.
Align iOS/macOS local glyph rasterization test fixture to Qt.
Prefer local fonts that match the names specified in the font stack (from the text-font layout property), except for the last resort fonts that mbgl hard-codes. Fall back to the list of fallback CJK fonts in user defaults, then the fonts passed in through the platform-agnostic interface (that come from Info.plist). Explicitly use the first font descriptor in the cascade list instead of the system default of Helvetica.
Since the font stack can vary from one rasterization operation to the next, avoid caching the resolved font for now. Removed null checks that are unrealistic given the Core Text API contract.
mbgl::Renderer and mbgl::MapSnapshotter can now contain a list of font family names, font display names, and font PostScript names, each name separated by a newline.
Introduce `Resource::minimumUpdateInterval` and consider it in the online file source.
The `minimumUpdateInterval` is used to throttle the requests, which were initiated due to resource expiration.
This changes image size properties to be scales instead of pixel sizes.
The commit also adds fixes for handling image updates with the same ID,
adds tests for expressions in paint properties, as well as tests for using images
with pixel ratio greater than 1.
Finally it moves image-tilt-displacement and perspective-compensation properties
from layout to paint properties, and includes other minor cleanups.
This change introduces a new property type, Rotation, that uses
a custom interpolator, and that is currently applied to
all style properties named "bearing", with a period attribute.
