lgtm w/ comment and rename requests. And we should delete the STArray rather
than comment it out.

File src/gpu/GrAtlasTextContext.cpp (right):

https://codereview.chromium.org/1088533002/diff/40001/src/gpu/GrAtlasTextCont...
src/gpu/GrAtlasTextContext.cpp:784: struct Geometry {
SubRunGeometry?

https://codereview.chromium.org/1088533002/diff/40001/src/gpu/GrAtlasTextCont...
src/gpu/GrAtlasTextContext.cpp:1013: static const int kMinAllocated = 32;
min allocated for what? is it a count or a bytes?

https://codereview.chromium.org/1088533002/diff/40001/src/gpu/GrAtlasTextCont...
src/gpu/GrAtlasTextContext.cpp:1014: size_t instanceCount() const { return
fInstanceCount; }
instances of what?

https://codereview.chromium.org/1088533002/diff/40001/src/gpu/GrAtlasTextCont...
src/gpu/GrAtlasTextContext.cpp:1017: Geometry& geometry() { return fGeoData[0];
}
comment about why we have a getter just for the first?
