This change introduces the CanvasEngine::All type to automatically
initialize the engines available on the current system.
These revisions improve the usability of these APIs.
Addtions:
- enum class CanvasEngine::All
Modifications:
- Result Initializer::init(CanvasEngine engine, uint32_t threads) ->
Result Initializer::init(uint32_t threads, CanvasEngine engine = tvg::CanvasEngine::All)
replaced 32-bit operations with 8-bit operations for masking buffers.
We might need a grasycale image support for applying 1-byte channel masking input(Picture).
Some of masking implementation are disabled by this reason.
Also, I don't expecct it's necessary for the thorvg now.
Corrected subtract/intersect masking behaviors that were inaccurately functioning
within chain-masking.
This also helps to enhance the masking performance by reducing the
masking region when applying subtract/intersect.
