renderer: rectified the fast track for clipping

Browse source 
- Issue was present when masking and clipping were applied
simultaneously. In the case where the mask was in fastTrack
mode and the clip was also clipped, the fastTrack was not
reset, resulting in an incorrect rendering effect.

- For rectangular clippers with a stroke width > 0, stroke clipping
should be applied. However, the fastTrack mode was set instead,
resulting in regular clipping instead of stroke clipping.
