Subject: [PATCH] Bug 697500: Fix NULL ptr access.
|
||||
|
||||
Cope better with errors during rendering - avoid letting the
|
||||
gstate stack get out of sync.
|
||||
|
||||
This avoids us ever getting into the situation of popping
|
||||
a clip when we should be popping a mask or a group. This was
|
||||
causing an unexpected case in the painting.
