Features and improvements

• Add showUserHeading option to GeolocateControl that draws a triangle in front of the dot to denote both the user's location, and the direction they're facing.(#10817) (h/t to @tsuz)

• Add support for text-writing-mode property when using symbol-placement: line text labels.

  • Note: This change will bring the following changes for CJK text blocks:

    • 1. For vertical CJK text, all the characters including Latin and Numbers will be vertically placed now. Previously, Latin and Numbers were horizontally placed.

    • 1. For horizontal CJK text, there may be a slight horizontal shift due to the anchor shift.

• Improve character alignment in labels with mixed CJK and Latin characters by adding support for descender and ascender font metrics.

• Improve terrain performance by reducing number of framebuffer switches during draping.

• Improve terrain performance by prioritizing allocation of large render cache batches.

• Improve behavior of vertically aligned line labels with horizontal text by adding stickiness to their flip state, preventing them from flickering.

Bug fixes

• Fix a potential rendering artifact when using custom fill-extrusion dataset with terrain.

• Fix anchor calculation for line-center line labels when the anchor is very near to line segment endpoints.

• Fix ImageSource breaking in Firefox/Safari if it's not immediately visible.
