SDF text rendering

🎯 Recommended outlineSize Range for SDF Rendering

Use Case	Suggested Maximum Range	Notes
UI text rendering	1.0 – 5.0	Keeps edges sharp; ideal for buttons, labels, and interface elements
Headings or large fonts	5.0 – 10.0	Allows thicker outlines; watch for blur or aliasing
Special effects (e.g. glow, stroke)	10.0 – 20.0	Good for visual effects; may require shader optimization
Extreme or experimental effects	>20.0	Can cause distortion or performance issues; use with caution

⚠️ Key Considerations

• SDF texture resolution: Larger outlineSize values may exceed the precision of the SDF texture, leading to blurry or distorted edges.
• Font size: Applying a large outline to small fonts can cause the outline to overwhelm the glyphs.
• Performance impact: Bigger outlines can increase GPU load, especially when rendering lots of text.

✅ Practical Tips

If you're encountering issues like edge distortion or unclear strokes, try the following:

• Start with outlineSize = 1.0 and gradually increase.
