A free pascal client for opengaze api

[cpicanco]

Hi everyone!

I am sharing a client to communicate with Gazepoint eye tracker. It is really simple right now. You can connect and control the Gazepoint Control server using calibration and record commands:

Recent commits introduce calibration choreographies for remote and local setups

Recent commits introduce a worker thread to fix a bug in the blocking logic, which was causing long strings to be partially lost.

# Incoming thread
https://github.com/cpicanco/fpc-opengaze/blob/cedae7e6585740e79137a54d2df77f2868b4cc33/src/opengaze.incoming.pas

The TCP/IP client receives strings from a server running at 150 Hz. After this low-level (synaser) processing, the client's incoming thread splits the received strings into "commands" using #13#10 as a constant separator. Partially received commands, if any, are saved for the next receive round. Full commands are enqueued into a thread-safe list.

# Worker thread
https://github.com/cpicanco/fpc-opengaze/blob/cedae7e6585740e79137a54d2df77f2868b4cc33/src/opengaze.worker.pas

A worker thread that controls blocking versus non-blocking commands waits for commands and processes them until all command processing is complete.

I would greatly appreciate it if you could share your comments or suggestions.
