Converted to bitwise operators to improve performance at high volumes.
Converted math to bitwise operators to improve performance at high volumes.
Moved any repetitive mathematical operations outside the core loop and simplified accessors to allow for maximum JIT compile optimizations to take place.
Remove redundant calls to Math.round as it is called again within getPixelIndex in both cases.
… number Added operation to ensure 32-bit color output is interpreted as a positive integer.
Final operation can "re-negate" the value - moved the conversion to unsigned int to be after alpha integration into the value.
Also issues with high-bit values going from int to RGBA - fixed.

What's Changing and Why
Some functions have operations within loops that don't need to be and/or use floating point math where bitwise operators are faster. Performance is impacted when doing intense operations on large images.
What else might be affected
Nothing. The logic is exactly equivalent.
Tasks
None required - changes are entirely internal.
