// The process pipe is used to notify the host about process exits,
// also associate all process-owned host GL resources with a process unique ID
// (puid). This is for the purpose that the host  can clean up process resources
// when a process is killed. It will fallback to the default path if the host
// does not support it. Processes are identified by acquiring a per-process
// 64bit unique ID (puid) from the host.
//
// Calling processPipeInit will associate the current render thread with its
// puid in the host.
//
// This is called when creating rcEncoder.
