// class that handles low-level rendering operations, such as drawing pixels and shapes to the display.

// This class is framework-agnostic and focuses solely on manipulating a 1-bit per pixel buffer.

|
// Constructor Args:
|
|
// uint8_t* buffer: Pointer to the bit buffer
|
|
// int width: Display width in pixels
|
|
// int height: Display height in pixels
