This patch replaces the bespoke rendering engine in Presenter with a
simple pipeline that turns presentations into single-page HTML files.
The HTML is then loaded into an OutOfProcessWebView.
This achieves a number of things, most importantly:
- Access to all the CSS features supported by LibWeb
- Sandboxed, multi-process rendering
The code could be simplified a lot further, but I wanted to get the new
architecture in place without changing anything about the file format.
These functions return the deprecated `Core::File` class, so let's mark
it as such to avoid possible confusion between future non try_*
functions which will use Core::Stream family classes and to possibly
grab someone's attention. :^)
In 7c5e30daaa, the focus was "only" on
Userland/Libraries/, whereas this commit cleans up the remaining
headers in the repo, and any new badly-formatted include.
Base+Userland: Add menu item icons
This adds missing icons to Presenter Presentation menu.
This adds missing icon to Image Viewer View menu.
This adds a scale icon for the Image Viewer and Font Editor.
This moves the Fit Image to View icon to the 16x16 folder as it's now
used by Image Viewer and not only Pixel Paint.
This improves the fullscreen and play icons so that they fit together
better.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This version can already:
- load all of the defined file format except for the image type and the
frame-specific stuff
- navigate frames and slides (though frames are mostly stubbed out)
- display text with various common settings
- displays text with various fitting and scaling methods
- scale and position objects correctly no matter the window size
