Minor tweaks

Fix run-on sentence (thanks Daniel). Make link to stroke expansion paper point primarily to arXiv.

We decided in office hours today to make the scope strictly the month of April. There will be major news in May, not least of which the 0.1 release, but there will be separate publicity around that.

 [Parley] is our text layout crate, supporting variable fonts and other advanced features.
 Supporting Parley is [fontique], a crate for enumerating the system fonts and making them available for itemization (choosing the right font to support a particular script).

+In GPU rendering land, we have written a paper on GPU stroke expansion ([arXiv][stroke expansion arXiv], [repo][stroke expansion repo]) and submitted it to a conference.
 This paper explains quite a bit of the math behind Vello's path rendering, and explains how we adapted it for high performance on the GPU.
 It's also a good time to note the [wgpu 0.20] release, which contains some work on suboptimal zero initialization that will dramatically improve startup time on many platforms, including Android ([wgpu#5508]).
 It also has support for subgroups, which will unblock further performance improvements in Vello.
 
-We're very much looking forward to participating in RustNL 2024, where Raph will present a talk on Xilem, and we also look forward to meeting with representatives of other projects in the Rust UI ecosystem to find common ground and possibilities to collaborate.
