LayerTransactionParent::RecvGetTransform takes care to reverse all the
transformations applied by AsyncCompositionManager::SampleValue to the CSS
values calculated so that it can return CSS values for testing. However, it
fails to revert the conversion from CSS pixels to device pixels applied to the
translation components of the transform by
nsStyleTransformMatrix::ProcessTranslatePart as called by
nsDisplayTransform::GetResultingTransformMatrix.
This patch converts the resulting transform's translation components from device
pixels back to CSS pixels. It also adds documentation for the other operations
in LayerTransactionParent::RecvGetTransform.
