This was a bit jarring, and didn't align with the behavior of other PDF
renderers.

PDFViewer: Clear rendered page cache on application resize
...
When resizing the application, the pages are expected to grow or shrink
proportionally. This means that after a resize, we need to rerender
every page.

Applications: Change static constexpr variables to constexpr
...
Function-local `static constexpr` variables can be `constexpr`. This
can reduce memory consumption, binary size, and offer additional
compiler optimizations.

PDFViewer: Add actions to rotate the displayed PDF
...
This implements the rotate cw/ccw actions in PDFViewer.
Since the rendered pages are stored in a HashMap for caching,
the bitmap is wrapped in a struct with the current rotation.
This way the caching works as expected while zooming, and a new bitmap
is rendered when the page is rotated.

Everywhere: Use 'decrease_slider_by()' method from AbstractSlider
...
The same idea as 'increase_slider_by()', it helps us to avoid repeating
the pattern 'set_value(value() - delta)'.

PDFViewer: Allow zooming in and out + scrolling
...
When holding ctrl and scrolling, the page will be zoomed in an out.
When zoomed in on a page, scrolling with move vertically up and down
the page (or horizontally if shift is being held).
In order to speed up zooming, zoomed bitmaps are cached per-page at
each distinct zoom level. This cache is cleared every 30 seconds to
prevent OOM problems.
