## Description

Alacritty is a cross-platform terminal emulator and command line interface designed for high visual throughput. It functions as a GPU-accelerated text renderer that uses OpenGL to offload the drawing of the terminal interface to the graphics card.

The project focuses on high-performance text rendering to ensure low input latency and smooth interface updates. This is achieved through hardware-accelerated text rasterization and the use of a GPU-accelerated rendering engine to display terminal output.

The application maintains consistent behavior across different operating systems via a cross-platform abstraction layer. Its runtime behavior and visual appearance are defined through user-defined settings loaded from external configuration files.
