Summary

Format with clang-format with a combination of Chromium and Microsoft styles.

Styles

• Base style: Chromium.
• PointerAlignment and indent widths from Microsoft.
  • Right pointeraligned provides unmistakable clarity on vars.
  • Indent width of 4 provides better readability.
• Disable BinPacking on args to ensure attributes and the likes formatted more read-friendly.
• AccessModifierOffset: -4 aligning with BTC (webkit standard) to be more in line with BTC - as it's a non functional decision that stands out.
