v11.28.0-rc.1

Introduce LineLayer.lineBorderGradient API to color the border of a line feature with a gradient along its length. Takes precedence over lineBorderColor and requires lineBorderWidth to be greater than zero.
Expose line-border-width and line-border-color as public paint properties. They were previously hidden from the style specification.
Expand the valid field-of-view range from [11, 90] to [1, 90] degrees, allowing much narrower camera FOVs.

Fix 3D models with a zero vertex alpha channel being rendered fully black.
Fix double rotation of the FF5C (fullwidth vertical line) character in vertical text.
Fix tile pack patch application failing when disk space runs out mid-write; the disk quota is now checked and eviction triggered before the patch is applied.
Internal fixes and performance improvements.
