* fix(font): Remove the unnecessary and duplicated inclusion
and correct some wrong comment too
* fix(font): Handle the out of memory gracefully in decompression case
and remove the check of gdsc since it is impossible to become null
* fix(font): Use the correct type to avoid the cast and shift
* fix(font): Change the bit field width to occupy the whole byte
* fix(font): Correct _LV_STR_SYMBOL_ generation command
and add _LV_STR_SYMBOL_BULLET to the list
* fix(font): lv_font_load shouldn't call lv_fs_close if lv_fs_open fail
* fix(font): read_bits should return 0 not -1 in error case
to avoid read_bits_signed waste time to extend the sign bit
* fix(font): Correct the return type of read_bits to unsgined int
and extend the sign bit more efficient and correct
* fix(font): Sync LV_FONT_FMT_TXT_CMAP_ value to binary font spec
and then remove the hard code value from source code:
https://github.com/lvgl/lv_font_conv/blame/master/doc/font_spec.md#L96
remove zero fields statement too since font_dsc->cmaps already zero at line 334.
* fix(font): Improve the performance by reading cmap table by once
* fix(font): Improve the loading performance if the header is multipled by 8bits
* fix(font): Read loca table in batch if the size is 32bits
* fix(font): Load the underline related attributes
spec here:
https://github.com/lvgl/lv_font_conv/blame/master/doc/font_spec.md#L55-L56
* fix(task): Remove the unnecessary cast and init
and correct the comment too
* fix(task): Implement lv_task_create directly
to avoid lv_task_set_prio which is a time consuming operation.
* fix(task): Exclude the return value computing from the idle time
and change handler_start and time_till_next to local variables
* fix(task): Remove zero task_deleted and task_created in lv_task_exec
since the loop in lv_task_handler already do the same thing
* fix(color): Return the opposite value in lv_color_premult when LV_COLOR_DEPTH equals 1
and correct the comment too
* fix(color): Correct the comment and alignment issue
* fix(color): Remove LV_COLOR_[SET|GET]_G16_SWAP
to simplify LV_COLOR_16_SWAP process
* fix(color): Correct the cast usage
* fix(color): Remove LV_MATH_ABS in lv_color_rgb_to_hsv
since delta can never become a negative number
* fix(color): Align LV_COLOR_[SET|GET]_A1 with other similar macro
* fix(area): Correct r_sqrd and dist(int32_t to uint32_t)
since these two variables never become negative
* fix(area): Return early in _lv_area_is_in if pointer outside area
The origin code always does the full check if radius != 0, but it
is unnecessary when is_in equals true.
* fix(mem): Utilize ALIGN_MASK as much as possible
to avoid check LV_ARCH_64 again and again and
correct the comment about MEM_UNIT
* fix(mem): Simplify _lv_memset implementation by SET8/SET32/REPEAT8 macro
* fix(mem): Handle the out of memory gracefully in _lv_mem_buf_get
don't modify the state in the failure
* fix(mem): Remove the unnecessary memset, memcpy and assignment
* Move LV_GC_INCLUDE to the common place(gc.h)
to avoid the duplication in many source files
* fix(theme template): Always initialize _lv_theme_material_styles
just like what other theme do
* fix(fs): Check driver ready in lv_fs_dir_open and lv_fs_free_space
* fix(fs): Avoid the memory leak in lv_fs_open and lv_fs_dir_open
* fix(fs): Fix typo error in lv_fs_trunc(tell_cb should be trunc_cb)
* fix(fs): Make lv_fs_dir_close same as lv_fs_close when dir_close_cb equals NULL
* fix(fs): Handle the struct cleanup correctly
* improve(fs): Don't allocate memory when file_size or rddir_size equal zero
pass the address of file_d or dir_d to open_cb or dir_open_cb instead, so
implementor can point file_d/dir_d to other location. In many cases(POSIX),
file system will allocate the context for us, this improvement could avoid
we allocate the 4/8 bytes intermediate space.
* fix(async): Move lv_async_info_t from lv_async.h to lv_async.c
since the user don't need know the implementation detail
* fix(async): Don't set user_data again
since lv_task_create already save it for us
