For tip of tree
Test 1 - half pixel rendering
Adjust the positions of the glyph quads so they never land on a 1/2
pixel position. Having a 1/2 pixel position causes some drivers to
point sample the glyphs poorly because the round differently for
different pixels.
Test 2 - smooth scrolling
Move a textblob very slowly in y to make sure in matches a freshly
constructed textblob.
Fix:
Regen the GrTextBlob if the translation is not by whole pixels.

motivation: BUILD.gn os too big, also can be reused in modules.
Also: add a BUILD.gn for minimal_ios_mtl_skia_app that uses the
template.

This change adds another layer of complexity and control to
the particle system. There are now two code chunks: the old
code that's run per-particle, and new code that's run for
the effect itself. This allows for effect lifetime to be set
by the script (eg, randomly), as well as the emission rate.
Rate can vary over time (see pulse.json), and particles can
be emitted in bursts by setting the effect's burst field
(see fireworks.json).
Additionally, the effect has its own frame of reference and
color, which becomes the default state for newly emitted
particles. This allows synchronizing state across particles
in various interesting ways (see color in fireworks.json).
