[GANESH] AA DrawPath writes outside a non-AA clipRect on GPU

[vulapu yashwanth]

Hi Team,

Ganesh’s GPU backend renders fractional coverage one pixel outside an explicit non-antialiased clipRect. The same code renders cleanly with Skia’s raster backend. 

Fiddle code:- https://fiddle.skia.org/c/0bf08688385f15dfa1b4a350b72bfea8

The clip starts at x=100, but the GPU output contains fractional white coverage at x=99.

Expected: pixel x=99 remains black because it is outside the clip.

Could you please confirm whether this is expected and suggest the correct way to prevent drawing outside the clip?

Thanks.
