Thanks, added some docs suggestions

Suggested change

	//! # Framebuffer
	//!
	//!
	//! A framebuffer can be used to contain new pixels of a new frame before being displayed.
	//!
	//! Some display driver write pixels directly on the display, which can cause some screen tearing.
	//!
	//! Mousefood can provide a framebuffer ready to be used.
	//! # Framebuffer
	//!
	//! A framebuffer implementation for storing pixels in memory before rendering to a display.
	//!
	//! This module provides [`HeapBuffer`], a heap-allocated framebuffer that can be used
	//! with display drivers that don't provide their own internal framebuffer. This helps
	//! prevent screen tearing by allowing you to compose a complete frame in memory before
	//! sending it to the display.

Suggested change

	/// Framebuffer holding pixels, waiting to be drawn to the real display.
	///
	/// Created to be used in mousefood with a display driver not providing an internal framebuffer.
	/// A heap-allocated framebuffer for storing pixels before rendering to a display.
	///
	/// `HeapBuffer` provides a memory-based framebuffer that can be used with display drivers
	/// that don't have their own internal framebuffer. This helps prevent screen tearing by
	/// allowing you to compose a complete frame in memory before sending it to the display.
	///
	/// The framebuffer is generic over any pixel color type that implements [`PixelColor`]
	/// and [`Copy`]. It stores pixels in a contiguous `Vec<C>` arranged in row-major order.
	///
	/// # Type Parameters
	///
	/// * `C` - The pixel color type. Must implement [`PixelColor`] and [`Copy`].

Suggested change

	/// Create a new framebuffer with defined dimensions
	///
	/// # Arguments
	///
	/// * `bounding_box` - The dimensions of the framebuffer
	/// Creates a new framebuffer with the specified dimensions.
	///
	/// The framebuffer is initialized with a background color derived from [`Color::Reset`].
	///
	/// # Arguments
	///
	/// * `bounding_box` - A [`Rectangle`] defining the position and size of the framebuffer.
	/// The framebuffer will have `width × height` pixels, where width and height
	/// are taken from the rectangle's size.
	///
	/// # Returns
	///
	/// A new [`HeapBuffer`] instance with the specified dimensions, initialized with
	/// the default background color.
	///
	/// # Memory Usage
	///
	/// This method allocates `width × height × sizeof(C)` bytes of memory on the heap,
	/// where `C` is the pixel color type.

(I know these are more detailed than most docs in the project. I want to rewrite all docs before v0.3 release.)

It's all good! Thanks for the better docs!
