Reason for revert: failed assertion "fXTiles * fYTiles != 0" Original issue's description: > Use BBH reserve hook to preallocate space for tiles. > > Before getting too far into changing how SkTileGrid stores its tiles, I figured I'd > better see how much I can tweak out the existing format. Cleverly, that way > any improvements I make by changing the format will look that much less > impressive. > > This CL looks like it will be a 5-15% win in time spent recording, with no effect > on playback. > > This CL also shrinks the tiles to fit exactly when we're done inserting, > using newly added SkTDArray::shrinkToFit(). It's quite cheap to run (maybe > taking back 1-2% from those 5-15% wins), and means we'll lug around about 15% > fewer bytes in the tile grids. Note though this strategy temporarily uses up to > 30% more memory while building the tile grid. For our largest SKPs, that's > maybe 75-100K extra. > > BUG=skia: > > Committed: https://skia.googlesource.com/skia/+/52455cbc02d7f480d988ae7cdacc11ad69078c2c TBR=reed@google.com,robertphillips@google.com,mtklein@chromium.org NOTREECHECKS=true NOTRY=true BUG=skia: Review URL: https://codereview.chromium.org/642933002 |
