説明

Looking at the gl driver code for drawing primitives, it appears everything is rasterized in software, and then OpenGL is only used to draw the resulting rasters to the screen. Since there is an OpenGL dependency anyway, why not use OpenGL to draw the primitives? It must have been considered. Is it something planned for the future? Are there strong reasons not to?

調査方針
The issue is a discussion about replacing software rasterization with OpenGL for drawing primitives in Fyne's gl driver. The current implementation in the gl driver uses software rendering and then uploads to OpenGL. To implement this, one would need to study the existing gl driver code (likely in internal/driver/gl/), understand how primitives are drawn, and evaluate the feasibility and performance implications of using OpenGL directly. The discussion in the comments includes various perspectives on the trade offs, so reading through the comments is essential to understand the context and any blockers.
