Overhauls text rendering to improve performance. Renderer was really ineffient, sending a separate GPU draw call for every character rendered. This created a bottleneck, especially with text-heavy UI stuff like the wallpaper. - The 'TextRenderer' now generates a single texture atlas for all font glyhs on load so all characters share a single texture. - 'begin()' / 'flush()' was added to the 'TextRenderer'. Calls to 'render_text' now buffer vertex data (position, texture coords, colour) instead of drawing immediately. A single 'flush()' call at the end of a pass draws all buffered text in one draw call. - A simple batching introduced some shitty visual layering bugs. to solve this, a staged flushing architecture has been implemented. Each logical UI component is now responsible for managing its own rendering passes, beginning and flushing text batches as needed to ensure correct back-to-front layering. |
