Allow translucent RenderNode->Bitmap captures

Set translucent to true when doing createHardwareBitmapFromRenderNode.
This ensures that the buffer is initialized to transparent which
is a safer default for this path. Marginally less performant in some
cases, but as this is a rare capture safety is preferred for and
performance can be revisted if it turns out to be an issue.
