Clipping spans are stored this way. clip_index has an index to the
|
|
spans (in clip_span) for each line. clip_span has the x-starting
|
|
coordinate for each span. A line starts 'off', each coordinate flips
|
|
the state. The spans are stored in increasing y order, so
|
|
clip_index[y+1]-1 is the index of the last span coordinate. Thus, if
|
|
clip_index[y]==clip_index[y+1], the entire line is clipped.
|
|
clip_index actually has clip_sy+1 entries, so clip_index[y+1] is
|
|
valid for _all_ lines.
|
|
|
|
All coordinates are in device space and counted inside the clipping
|
|
rectangle.
|
|
|
|
To make things easier, each line also ends in the off state (so the
|
|
last entry in clip_span might be a dummy entry at the end of the
|
|
line).
