Implementation Notes

TODO

Function that add a curved subpath to the current drawing path (for example: context.arc()) need to be transformed by the current transformation matrix. Right now, only the points are being transformed, and not radius, etc.
globalCompositeOperation = lighter and copy don't have a direct equivalent in Swing Graphics. Needs custom implementation. Java implementation is different from the HTMLcanvas implementation. *Following APIs are yet to be implemented:
- Config APIs
  - font
  - textAlign
  - textBaseline
  - measureText
  - createRadialGradient
  - createPattern
  - shadowOffsetX
  - shadowOffsetY
  - shadowBlur
  - shadoeColor
- Draw APIs
  - drawFocusIfNeeded
  - strokeText
  - drawImage
- Interaction and Animation
  - isPointInPath
  - addHitRegion
  - removeHitRegion
  - clearHitRegion
