- If `w3m` or `imagemagick` aren't installed we gracefully fallback to ascii mode.
- Automatically find the `w3mimgdisplay` path and fallback to ascii mode if not found.
- Automatically find the `w3m-img` path and fallback to ascii mode if not found. \[1\]
- Fix padding escape codes on BSD systems.
- Swap escape codes from `\e` to `\033` for consistency.
- We only move the cursor to the bottom of the terminal in w3m/iterm2 rendering modes.

- Removed `--colors` as it was apparently broken from day 1.
- Usage has been reformatted so that every flag has a value.
\[1\] Setting `$w3m_img_path` will make the script look there first.

- Added `--ascii_distro` to choose which distro's ascii logo to display.
- Added `--ascii_colors` and `$ascii_colors` which allow you to change the colors of the ascii art<br \>
and distro logos. \[2\]
- Added `--size` and `$image_size` to set the image size in pixels.
- Rename `--shuffledir` and `$shuffledir` to `shuffle_dir`.
- Rename `--imgtempdir` and `$imgtempdir` to `thumbnail_dir`
- Removed `--split_size` and `$split_size` as they were weird and confusing to use.
- Default thumbnail directory is now `$HOME/.cache/thumbnails/fetch`. Thanks @tudurom
- If `--image` and `--ascii` are left empty we fallback to ascii distro mode.

If you don't know your font width in pixels keep trying values until the image is half the<br \>

Once `font_width` is set the image will by default take up half the terminal width. You can<br \>
use the launch flag `--size px` or change the config option `$image_size` to set it to a custom<br \>
size in pixels.
You can also use the launch flag `--font_width` to set it on the fly.
