Elevate lerp to 64 bits
...
For long lines, the linear interpolation for the current position could
overflow. This is the reason the length resolution is currently so
small, which sets a limit on the minimum pen speed. This change
introduces two 64-bit divisions, but allows for a larger length
resolution and lower pen speeds. The runtime is still pretty minimal.
