584807b4f5 Add runtime detection of V8 memory cage #3384 
When using the V8 memory cage, Buffers cannot be wrapped and then
later freed via a callback. When the cage is detected via a throw,
instead fall back to copying Buffer contents to V8 memory.

This approach will be used by Electron 21+ and you should expect
reduced performance and increased memory consumption/fragmentation.

e6bfa52b0b Add raw pixel data support to boolean and withOverlay ops 
The previously-scattered image opening logic has been refactored to a
single ImageDescriptor struct/Object available to both JS and C++ code

This removed about 150 LOC but more importantly reduces the complexity
of adding/exposing new operations that require an input image.
