Surface.createSimilar

Create a new surface that is as compatible as possible with an existing surface. For example the new surface will have the same fallback resolution and font options as other. Generally, the new surface will also use the same backend as other, unless that is not possible for some reason. The type of the returned surface may be examined with Surface.getType. Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.) Use Surface.createSimilarImage if you need an image surface which can be painted quickly to the target surface. Since 1.0
