Name	Type	Description
`u`	`struct _lv_draw_nanovg_unit_t *`	pointer to the nanovg unit
`entry`	`struct _lv_cache_entry_t *`	the FBO cache entry to release

Convert a cache entry to a framebuffer.

struct NVGLUframebuffer * lv_nanovg_fbo_cache_entry_to_fb(struct _lv_cache_entry_t *entry)

Name	Type	Description
