Performance

• Refactory the logic to handle force decode logic to avoid CA copy frame buffer, introduce SDImageForceDecodePolicy detailed control Refactory the logic to handle force decode logic to avoid CA copy frame buffer, introduce SDImageForceDecodePolicy detailed control #3559 Memory usage increases when webp is used after 5.13.0 #3417
• • This fix the issue that non-ImageIO coder (means, WebPCoder) will cause CA to copy bitmap buffers and increase memory usage.
• • You can still custom the behavior using the new SDImageForceDecodePolicy, defaults to automatic.
• For coder plugin who want to opt-in to avoid CA::copy_image, use the new preferredPixelFormat: and to do bytes alignment and colorspace convert.

Fixes
