> Can we remove the `#if LV_USE_DRAW_VG_LITE && LV_USE_VG_LITE_THORVG` conditions and just `return true`? I think it's OK.

It should be that the draw vector is only adapted to the full-screen buffer mode. For PARTIAL mode, the global matrix in `lv_vector_dsc_t` needs to be moved as a whole...

> [@FASTSHIFT](https://github.com/FASTSHIFT) we have discussed that the font manager will be extended beyond FreeType to support the built-in fonts too. ([#6806](https://github.com/lvgl/lvgl/issues/6806)). Will have time work on it in the near...

> @liamHowatt @FASTSHIFT can we reiterate on whether `lv_freetype_private.h` can be added to `lvgl_private.h`. Reading #6418 again I'm not entirely sure what the original problem was. How about we rename...

喔，我以为是那种用GPIO中断检测的普通的旋转编码器。这种要用配置定时器的特殊需求，还是用标准库实现，这样最灵活。 因为需要保证不同平台的可移植性和可维护性，所以只封装满足最常用的需求API。

Are there any examples of recurrence? Why pass a null pointer to `lv_obj_get_ext_draw_size`?

> The image generated by parsing BMP with vg_lite is blank, https://github.com/lvgl/lvgl/blob/master/tests/ref_imgs_vg_lite/libs/bmp_1.png @FASTSHIFT You can temporarily ignore this error because the vg_lite porting layer currently does not support the `lv_image_decoder_get_area`...

A very good start, but it is important to note that when merging, please do not lose existing functions, such as error parameter checking, path\matrix\buffer data structure printing functions, image_dsc/font...

I think the `LV_VG_LITE` prefix should be maintained, which is more in line with the lvgl naming convention, convenient and quick to search, and there will be no naming conflicts...
