A code is calling this – first – Golang code which in turn depends upon another – second – Golang code.

It’s intended to modify the second Golang code to fulfill a purpose. I wonder which option for the modification strategy would be quicker and less complex:

1. Create a new package and copy over all the source files and modify them from:
   • github.com/llgcode/draw2d/draw2dimg
   • github.com/golang/freetype/raster
2. Create GitHub forks of the original packages and modify them:
   • github.com/llgcode/draw2d/draw2dimg
   • github.com/golang/freetype/raster
3. Any other option?
