When the bounding boxes of a path and its clip are disjoint (i.e. they do not intersect) the result of their intersection is a negative rectangle. When calculating the intersection of the bboxes, the binning stage ensures that the bbox is non-negative. It then normalizes the coordinates to bin dimensions and rounds the top-left corner down to the neareast integer and the bottom-right corner up. However this rounding causes zero-area bounding boxes to have a non-zero area and sends the bottom-right corner to the placed in the next bin. This causes fully clipped out draw objects to be included in binning, with an incorrect clip bounding box that causes them to be erroneously drawn with partial clipping. `binning` now takes care around this logic to make sure that a zero-area intersected-bbox gets skipped and clipped out. `tile_alloc`, also takes care in its logic. Fixes #286 and #333 |
