2017-03-28Refcount all CFX_DIBSources (and subclasses) all the time.Tom Sepez
There are currently several ownership models for these objects, including ad-hoc logic for sharing and deletion, and the now-redundant CFX_DIBitmapRef externally-counted handle to the DIBs. Replace them all with the internal refcount scheme.

2017-03-27Verify available bits in bit streamDan Sinclair
The methods to read n bits from the huffman stream are not correctly checking that the bits are available. This means, we'll end up reading 0 bits due to the checks below and pretend like the read worked. This Cl adds the check that we are not at the end of the bit buffer before attempting the bit read.

2017-03-27Fix some ASAN issues in fx_skia_deviceNicolas Pena
- 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.

2017-03-27fix new tab crash in skia clip stackCary Clark
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.
