Do not notifyFinished on resources never loaded

If autoload images is disabled, the CachedImage element never starts
loading but still needs loading. We therefore need to check both
isLoading() and stillNeedsLoad() to determine if loading is complete.

This fixes a serious memory leak when autoload images is disabled.

Apply device pixel ratio to transparency layers

The transparency layers are currently created with taking hiDPI into
account. This means that any CSS opacity causes a shift in rendering
quality.

This patch forwards the device pixelratio for any QPaintDevice to
transparency layers created for that device.

Fix RenderGeometryMap.cpp ASSERT on Google Plus

The assert roundedIntPoint(result) == roundedIntPoint(rendererMappedResult)
is triggered on Google Plus. The cause appears to be premature rounding
leading a wrong result.

The fix is a to remove the early rounding. This follows a similar fix
in upstream WebKit r142638 where the same problem was fixed for the
other mapToContainer method.

Fix assert in BitmapTextureImageBuffer::applyFilters()

While WebCore should not give a BitmapTextureImageBuffer any filters
applyFilters() will still be called with an empty list of filters.

We should therefore not assert that applyFilters is never called by
that is only ever called with an empty list of filters to apply.

Fix assert in m_stack.isEmpty() in GraphicsContext::~GraphicsContext()

Save and restore is not balanced in GraphicsContext. This causes
the log error "ERROR void GraphicsContext::restore() stack is empty"
and assert in the GraphicsContext destructor.

The cause is a mismatch of GraphicsContexts being saved and restored by
TextureMapperImageBuffer beginClip and endClip. This patch fixes endClip
to restore the currentContext beginClip saved.

Fix transform of accelerated layers on hiDPI painters

A mismatch of reading combinedTransform but setting worldTransform
means that the pattern of only storing and restoring the transform
when temporarily overriding it, causes the hiDPI transform that

Fix memory leaks in platform/image-encoders/JPEGImageEncoder.cpp

https://bugs.webkit.org/show_bug.cgi?id=118781

Reviewed by Brent Fulgham.

We can find the function "jpeg_finish_compress" call the function "jpeg_abort" at the end.
And the comments of "jpeg_abort" is "Abort processing of a JPEG compression operation,
but don't destroy the object itself". (We can find these in the "jcapimin.c" of jpeg)
So the compression object destroy need be called.
No new tests because this doesn't change functionality.
