Previously we would unconditionally fetch all images via HTTP to grab
original sizing from cooked post processor in 2 different spots.
This was wasteful as we already calculate and cache this info in upload records.
This also simplifies some specs and reduces use of mocks.
Fixes two issues:
- ignores invalid XML in custom icon sprite SVG file (and outputs an error if sprite was uploaded via admin UI)
- clears SVG sprite cache when deleting an `icons-sprite` upload in a theme
* FIX: Allow SVG uploads if dimensions are a fraction of a unit
`UploadCreator` counts the number of pixels in an file to determine if it is valid. `pixels` is calculated by multiplying the width and height of the image, as determined by FastImage.
SVG files can have their width/height expressed in a variety of different units of measurement. For example, ‘px’, ‘in’, ‘cm’, ‘mm’, ‘pt’, ‘pc’, etc are all valid within SVG files. If an image has a width of `0.5in`, FastImage may interpret this as being a width of `0`, meaning it will report the `size` as being `0`.
However, we don’t need to concern ourselves with the number of ‘pixels’ in a SVG files, as that is irrelevant for this file format, so we can skip over the check for `pixels == 0` when processing this file type.
* DEV: Speed up getting SVG dimensions
The `-ping` flag prevents the entire image from being rasterized before a result is returned. See:
https://imagemagick.org/script/command-line-options.php#ping
* FIX: Be able to handle long file extensions
Some applications have really long file extensions, but if we truncate
them weird behavior ensues.
This commit changes the file extension size from 10 characters to 255
characters instead.
See:
https://meta.discourse.org/t/182824
* Keep truncation at 10, but allow uppercase and dashes
SVG files can have dimensions expressed in inches, centimeters, etc., which may lead to the dimensions being misinterpreted (e.g. “8in” ends up as 8 pixels).
If the file type is `svg`, ask ImageMagick to work out what size the SVG file should be rendered on screen.
NOTE: The `pencil.svg` file was obtained from https://freesvg.org/1534028868, which has placed the file in to the public domain.
`convert_to_jpeg!` is only called if `convert_png_to_jpeg?` and/or `should_alter_quality?` is true.
`convert_png_to_jpeg?` can be disabled by setting `SiteSetting.png_to_jpg_quality` to 100.
However, `should_alter_quality?` could be true if `SiteSetting.recompress_original_jpg_quality` was lower than the quality of the uploaded file, regardless of file type.
This commits changes `should_alter_quality?` so that uploaded png files will use the `SiteSetting.png_to_jpg_quality` value, rather than ``SiteSetting.recompress_original_jpg_quality` value.

* Also fixes an issue where if webp was a downloaded hotlinked
image and then secure + sent in an email, it was not being
redacted because webp was not a supported media format in
FileHelper
* Webp originally removed as an image format in
https://github.com/discourse/discourse/pull/6377
and there was a spec to make sure a .bin webp
file did not get renamed from its type to webp.
However we want to support webp images now to make
sure they are properly redacted if secure media is
on, so change the example in the spec to use tiff,
another banned format, instead
This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.
## Core
- Adds an SiteIconManager module which manages automatic resizing and fallback
- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon).
- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.
- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations
## Wizard
- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload
- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"
- Various copy updates to support the changes
- Remove the "upload-time" resizing for `large_icon`. This is no longer required.
## Site Settings UX
- Move logo/icon settings under a new "Branding" tab
- Various copy changes to support the changes
- Adds placeholder support to the `image-uploader` component
- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings
- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name
## Dashboard Warnings
- Remove PWA icon and PWA title warnings. Both are now handled automatically.
## Bonus
- Updated the sketch logos to use @awesomerobot's new high-res designs

This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.
To ensure safety we only apply this optimisation to images smaller than 500k.
This commit also makes a bunch of image specs less fragile.
This also adjusts the algorithm to expect
- 30% saving for JPEG conversion
AND
- Minimum of 75K bytes saved
The reasoning for increase of saving requirements is cause PNG may have been
uploaded unoptimized, 30% saving on PNG is very possible
In the past the filename of the origin was used as the source
for the extension of the file when optimizing on upload.
We now use the actual calculated extension based on upload data.
