Description of the feature or fix
linear grad in vg-lite is simulated using image, which means that
vg_lite_clear_gradcannot be called immediately after callingvg_lite_draw_gradto free the image memory because the GPU may not have finished drawing.Therefore, I introduced cache for management. On the one hand, it can reduce the overhead of frequently creating grad image images, and on the other hand, it can solve the problem of using after free asynchronous rendering by using delayed release.
