include/gpu/GrContext.h:145: void setTextBlobCacheLimit(size_t bytes);

question, otherwise lgtm

File src/gpu/GrTextBlobCache.h (right):

https://codereview.chromium.org/1264283002/diff/20001/src/gpu/GrTextBlobCache...
src/gpu/GrTextBlobCache.h:134: void setBudget(size_t budget) { fBudget = budget;
}
Do you need to purge if budget < fBudget?
