- Flush is needed in ~CFX_FxgeDevice, otherwise it may be called after deleting
the bitmap, when calling the destructor of the skia device driver.
- SkDashPathEffect::Make copies the given intervals instead of owning them, so
free the input to that method.
- If StartDIBits creates a new CFX_ImageRenderer, then the corresponding
CancelDIBits needs to delete the handle.

The crash on the new tab page is triggered by processing a transparency.
This creates a new Skia device in CPDF_RenderStatus::LoadSMask():
// cpdf_renderstatus.cpp # 2557
if (!bitmap_device.Create(width, height, format, nullptr))
which sets the Skia clip stack to empty.
It then calls
RenderObjectList()
RenderSingleObject()
ProcessClipPath()
which resets the clip stack;
// cpdf_renderstatus.cpp # 1882
m_LastClipPath = ClipPath;
m_pDevice->RestoreState(true);
At this point m_LastClipPath contains {m_Ref={m_pObject={m_pObj=empty } } }
The impelemntation in CFX_AggDeviceDriver::RestoreState() is
// fx_agg_driver.cpp # 1283
if (m_StateStack.empty())
return;
This hides unbalanced save/restores, but reworking PDFium to balance is nontrivial.
