Do we want a similar method on the shader caps, or is the idea to override
shader caps in this function as well?

I think we'd do it here as well. I added a stub function to GrShaderCaps to
apply overrides. It doesn't do anything currently.

+    fMaxTextureSize = SkTMin(fMaxTextureSize, options.fMaxTextureSizeOverride);
+}

 static SkString map_flags_to_string(uint32_t flags) {
     SkString str;
     if (GrCaps::kNone_MapFlags == flags) {
         str = "none";
     } else {
         SkASSERT(GrCaps::kCanMap_MapFlag & flags);
         SkDEBUGCODE(flags &= ~GrCaps::kCanMap_MapFlag);
         str = "can_map";
 
         if (GrCaps::kSubset_MapFlag & flags) {
