Update WR (gradients, batching, text run, border changes).

Browse source 
- Tidy and optimize the batching code.
- Support tiling / repeat for linear and radial gradients.
- Fix some edge cases of subpixel text AA.
- Add clip mask support to border shaders.
- Optimization to text run creation on CPU.
- Handle more box-shadow clipping cases.
- Fix a panic that could occur when window size is 0.
- Clip / scroll API improvements.
