[Draft] Screen recorder component

[pawelbudziszewski]

A component that captures the outcome of the rendering pipeline and saves it into png files on the local drive. Frames are recorded in defined intervals in the game mode.

Parameters:

• Enable screen capturing - if turned on, frames will be recorded after entering game mode.
• Output image path - path and file name (without extension) where files will be saved. It may be relative or absolute. Relative path will be resolved in reference to "{project_path}/Cache/{linux|windows|...}". WARNING: "~" is not recognized as user's home.
• Capture framerate - desired capture framerate - it won't be higher than this value. This framerate corresponds to simulation time, which can be scaled using "Tick scale" parameter. If this framerate is lower or equal to zero, frames will be captured without limit.
• Tick scale - simulation time scaling coefficient. 1.0 means no scaling. This parameter can be used to slow down the simulation time if more fps are required.

The system does not wait till the screenshot is saved, so if the capture framerate is set too high or the simulation runs too slow, some frames may be skipped. In such cases, it is advised to lower the tick scale.
