R3D Roadmap

v0.9

[x] Refactor internal r3d_draw module Centralize all drawing-related functionality and drawable objects, including VAO management, which is currently scattered.
[x] Redesign internal shader macro system ~~Rethink the current macro-based approach for managing shaders to improve clarity and maintainability.~~ The subject involves much more complexity than expected, it will probably remain as it is, the naming has at least been made clearer.
[ ] Explore alternative SSGI approaches The current SSIL-VB used as a cheap SSGI solution is far from ideal and difficult to tune. Investigating more stable and production-ready SSGI techniques would be beneficial.
[ ] Add more anti-aliasing options Provide higher-quality anti-aliasing solutions in addition to FXAA. SMAA appears to be the most suitable next step. Techniques such as TAA currently require deeper architectural changes...
[x] Material loading/import helpers Similar to existing skeleton and animation loading utilities, it would be useful to provide helper functions to import materials from files when needed.
[ ] Review skybox generation Improve parameter structure and naming, add an optional debanding setting, and support shaders for skyboxes.
[ ] Consider R3D_Camera type (maybe) Think about introducing a dedicated camera type that handles cullMask per camera (instead of using global state) and manages near/far parameters directly, removing the last dependency on rlgl.

Investigate the integration of a velocity buffer and frame history, mainly for TAA and motion blur. The current begin/end rendering model makes this non-trivial.
Improve support for shadow/transparency interaction (e.g., colored shadows).
Implement Cascaded Shadow Maps (or alternative) for directional lights.
Make wiki pages for the repo, consider it for the release.
