roytam1 877b16186b import changes from `dev' branch of rmottola/Arctic-Fox:
- Bug 1157954 - Report each surface in the ImageLib SurfaceCache individually in about:memory. r=dholbert (3810a2b1f)
- Bug 1139641 - Return more information from SurfaceCache::Lookup and SurfaceCache::LookupBestMatch. r=dholbert (fdd62b01d)
- Bug 1177615 - Rip everything related to FLAG_DECODE_STARTED out of ImageLib. r=tn (818a77ac1)
- Bug 1153253 - move nsImageBoxFrame::mRequestRegistered to pack better with other members; r=dholbert (fe26ff0ce)
- Bug 1177604 - Stop delaying the load event for XUL images until the image is decoded. r=tn (6c0100f5a)
- Bug 1180931 (Part 1) - Allow sync size decoding for single core devices. r=tn (62eae65e3)
- Bug 1180931 (Part 2) - Allow sync size decoding for transient (i.e. multipart) images. r=tn (537dea273)
- Bug 1165009 - Bail in RasterImage::OnAddedFrame if we hit an error during decoding. r=tn (e9a85bf7d)
- Bug 1171356 - On B2G, retry image decodes that fail because allocation of the first frame failed. r=tn (06e712f65)
- Bug 1151166 - Fix two Coverity warnings in nsPNGDecoder.cpp. r=jrmuizel (848f4f0c2)
- Bug 857040 - Warn on bad CRC instead of error exit. r=joe (74a6438ab)
- Bug 1117607 - Make decoders responsible for their own frame allocations. r=tn (d224b33a8)
- Bug 1178274 - Don't enable decode-only-on-draw if the APZ pref is true but e10s is disabled. r=dvander (76ca02965)
- Bug 1177323 - disable decode-only-on-draw preference. r=seth (b6ac4e9b0)
- Bug 1183836 - Remove support for decode-on-draw-only. r=tn (af0b79370)
- Bug 1183852 - Only mark surfaces as used in the SurfaceCache if a caller requested exactly that surface. r=dholbert (e8d94d193)
- Bug 1176124 (Part 1) - Add a MatchType enum to LookupResult to let Lookup*() return more detailed information. r=dholbert (b3b7b01c0)
- Bug 1176124 (Part 2) - Add placeholder support to the SurfaceCache so we can avoid launching redundant decoders. r=dholbert (6fa4cae4d)
- Bug 1185582 - Back out bug 1171356, a hack to retry image decoding which is now useless. r=tn (0bac6a812)
- Bug 1155332 - If we don't have enough memory to fully decode an image, discard it immediately. r=tn (2adc2f8ea)
- Bug 1185592 (Part 1) - Remove obsolete logging macros. r=baku (b1e98c8a8)
- Bug 1185592 (Part 2) - Make RasterImage store the decoder type instead of the MIME type. r=baku (abce7fd06)
- Bug 1186667 - Correctly report IMAGE_DECODE_COUNT and IMAGE_MAX_DECODE_COUNT telemetry for only non-size decodes. r=tn (97bfbbc82)
- make WEBPDecoder comply Bug 1117607 - Make decoders responsible for their own frame allocation (03866748e)
- make JXR decoder crudely compliant to 1117607 and make it allocate its frame - can probably be improved (b804d6f67)
