The goal of this project is to provide high speed graphics with + minimal project setup complexity, to encourage new programmers, younger people, + and anyone else that wants to make fun things. + + However, olc::PixelGameEngine is not a toy! It is a powerful and fast utility + capable of delivering high resolution, high speed, high quality applications + which behave the same way regardless of the operating system or platform. + + This file provides the core utility set of the olc::PixelGameEngine, including + window creation, keyboard/mouse input, main game thread, timing, pixel drawing + routines, image/sprite loading and drawing routines, and a bunch of utility + types to make rapid development of games/visualisations possible. + + + License (OLC-3) + ~~~~~~~~~~~~~~~ + + Copyright 2018 - 2022 OneLoneCoder.com + + Redistribution and use in source and binary forms, with or without modification, + are permitted provided that the following conditions are met: + + 1.

You can also include PGEX includes and + defines in here too.
