+# TODO List for 2D Framebuffer Graphics Library (`fbgl`)
+
+## Core Rendering
+- [x] Implement pixel manipulation: set, get, and clear individual pixels with color data.
+- [ ] Implement basic shapes:
+  - [x] Draw lines.
+  - [ ] Draw rectangles.
+  - [ ] Draw circles.
+  - [ ] Draw ellipses.
+  - [ ] Draw polygons.
+  - [ ] Support filled versions of shapes.
+  - [ ] Support outlined versions of shapes.
+- [ ] Implement bitmap rendering:
+  - [ ] Render 2D images (bitmaps) to the framebuffer.
+  - [ ] Support transparency via alpha channels.
+  - [ ] Support transparency via a key color.
+- [ ] Implement text rendering using bitmap fonts.
+
+---
+
+## Color Handling
+- [ ] Support RGB color format.
+- [ ] Support grayscale color format.
+- [ ] Support indexed color format.
+- [ ] Add utility to convert between color formats.
+- [ ] Support alpha blending for semi-transparent rendering.
+
+---
+
+## Window and Viewport
+- [ ] Add windowing support:
+  - [ ] Define sub-framebuffers (windows) within the main framebuffer.
+  - [ ] Maintain independent clipping for each window.
+- [ ] Implement clipping to respect rendering boundaries.
+
+---
+
+## Utilities and Effects
+- [ ] Implement 2D transformations:
+  - [ ] Scaling.
+  - [ ] Rotation.
+  - [ ] Translation.
+  - [ ] Transform relative to origin or center.
+- [ ] Add optional anti-aliasing for smoother shapes and lines.
+- [ ] Implement image manipulation:
+  - [ ] Scale bitmaps.
+  - [ ] Crop bitmaps.
+  - [ ] Rotate bitmaps.
+- [ ] Implement gradients and patterns:
+  - [ ] Fill shapes with gradients.
+  - [ ] Fill shapes with pattern-based textures.
+
+---
+
+## Performance and Optimization
+- [ ] Optimize batch rendering to minimize CPU cycles.
+- [ ] Add hooks for hardware acceleration (optional).
+
+---
+
+## Integration
+- [ ] Provide initialization routines for creating and managing a framebuffer.
+- [ ] Ensure platform independence:
+  - [ ] Abstract hardware details for Linux framebuffer.
+  - [ ] Abstract hardware details for SDL2.
+- [ ] Add support for reading framebuffer content to standard image formats (e.g., BMP, PNG).
+- [ ] Add support for writing framebuffer content to standard image formats (e.g., BMP, PNG).
+
+---
+
+## Debugging and Diagnostics
+- [ ] Develop diagnostics tools to inspect pixel data.
+- [ ] Add debugging overlays (e.g., FPS, gridlines).
+- [ ] Implement graceful error handling for out-of-bounds operations with informative messages.
