v2.1.0

• Apply gamma correction to anti-aliased pixels. This makes the SDF-rendered text very slightly thicker and matches how browsers render the same text/font with HTML closer (by @xavierjs #61)
• Improve performance by ~10%.
• Fix glyph x alignment to use actual bounding box metrics, matching height behavior. #34
• Reintroduce using OffscreenCanvas by default where available, making TinySDF work in worker contexts. #35
• Better code comments to clarify logic. #10

⚠️ This release very slightly alters how text is rendered, which might require updating test expectations for downstream users.
