While this was a workaround for a docs.rs issue (Px/Lp are not
linked), I decided having the shorter import path would look better in
the examples.
It probably wasn't necessary to update all of the references in the
internal code, but I decided it was worth the consistency.
Debug printing widgets was quite verbose. While developing a widget, you
often want to see a full debug printout, but this feature assumes that
debug printing a WidgetInstance should show a summary of the widget, not
a full debug printout containing cached glyph information of every
label.
By default, summarize just calls Debug, but this extra layer allows
widgets to provide a more condensed summary and exclude details like
caches.
Originally, adding dbg!() around the theme example's UI yielded a
whopping 20,324 lines of text. The summary code only prints 3,858
lines.
I started making more changes, and I lost track of what was merge
related and what wasn't, so I committed the merge with what was staged,
but it probably didn't compile.
This is the remaining changes to get things back to a state I'm happy
with, mostly tweaking the constrast behavior.
measure() now is layout(). LayoutContext can either persist layout
information or be used temporarily for measurement. While this caching
is constantly thrown out currently, this is a step towards being able to
only re-layout widgets if they've been invalidated.
I decided scrolling a label would work better, so I loaded a source file
and noticed it wasn't rendering quite right in the label. It turns out
that the text wrapping was triggering despite the width in redraw being
the same as the measured amount. In short: sometimes the width I measure
can't be the width I set as the cosmic_text::Buffer size, because it
will cause it to wrap.
I've worked around it by caching the measured text for now. But it may
still show up in other situations and may require a more generalized
fix by seeing what else we can gleam from the glyphs being measured.
