LayerTiler.cpp misses an include which is needed in debug build.
#include "LayerMessage.h"

Will add it before landing.

Note, this originally had a piece that contained a hunk against LayerTiler.cpp.  I've split it up so that is now committed to master_33.  That should be included when you redo this Robin. https://bugs.webkit.org/show_bug.cgi?id=80161

Looks good, can be cleaned up some more.

> Source/WebCore/platform/graphics/blackberry/LayerTile.h:25
> +#include "IntRect.h"

Can be just forward references.

> Source/WebCore/platform/graphics/blackberry/LayerTileData.h:26
> +class LayerTileData {

Not sure if this tiny class deserves its own file. Could we put it in LayerTile.h?

> Source/WebCore/platform/graphics/blackberry/LayerTiler.cpp:153
> +        requiredTextureSize = IntSize(m_layer->contents()->width(), m_layer->contents()->height());

m_layer->contents()->size() should give IntSize too.

> Source/WebCore/platform/graphics/blackberry/LayerTiler.cpp:430
> +    }

I'd prefer:
if (result.second) // Successfully added the new job.
    return;

> Source/WebCore/platform/graphics/blackberry/LayerTiler.cpp:527
> +            FloatRect rect(-d, -d, 2*d, 2*d);

Watch spacing 2*d

> Source/WebCore/platform/graphics/blackberry/LayerTiler.h:41
> +class TransformationMatrix;

Not used? Please check all.

Good catch, fixed.

All unnecessary includes and forward declarations are removed.

Looks good, but needs one more round :)

> Source/WebCore/platform/graphics/blackberry/LayerTileIndex.h:68
> +template<> struct IntHash<WebCore::TileIndex> {

You probably don't need WebCore:: prefixes in this file.

> Source/WebCore/platform/graphics/blackberry/LayerTiler.cpp:153
> +        dirtyRect = IntRect(IntPoint(), requiredTextureSize);

IntPoint::zero

> Source/WebCore/platform/graphics/blackberry/LayerTiler.cpp:159
> +    if (requiredTextureSize.isEmpty() || dirtyRect == IntRect(IntPoint(), requiredTextureSize)) {

IntPoint::zero

> Source/WebCore/platform/graphics/blackberry/LayerTiler.cpp:648
> +IntSize LayerTiler::defaultTileSize()

It seems this is only used internally? If so you can make it a free, static function.

> Source/WebCore/platform/graphics/blackberry/LayerTiler.h:104
> +            : type(type)

This looks really confusing, can you add m_ to the member vars? This makes it clear which is which.

> Source/WebCore/platform/graphics/blackberry/LayerTiler.h:122
> +        static TextureJob setContents(const SkBitmap& contents, bool isOpaque) { return TextureJob(SetContents, contents, IntRect(IntPoint(), IntSize(contents.width(), contents.height())), isOpaque); }

IntPoint::zero

I removed 4 WebCore:: prefixes, the other WebCore:: prefixes in the WTF namespace can not be omitted.

My bad, I should have found this in the first round. All member variables have been prefixed now.

Done.
