* Add support for SkImageGenerator creating external texturesGravatar Stan Iliev2017-06-08

* Fold SkImageCacherator into SkImage_LazyGravatar Brian Osman2017-04-27
| | | | | | | | | | | | | | | SkImageCacherator still exists, but only as an interface implemented (solely) by SkImage_Lazy. The only external clients are GrImageTextureMaker and SkImage_Gpu::getDeferredTextureImageData. This is probably an improvement, but doesn't go as far as I'd hoped.

* Simplify SkImageCacherator slightlyGravatar Brian Osman2017-04-24
| | | | | | | | | | | | | | - lockAsBitmap supported reading back textures to a bitmap, but this was only used by one GM. Removed all of that code, and merged the two bitmap functions together. - To make the GM cleaner, don't use SkImageCacherator directly - construct actual images.

* Rename SkImage_Generator to SkImage_LazyGravatar Brian Osman2017-04-20
| | | | | | | | | | | | | | This removes a long-standing source of confusion: SkImage_Generator was an image that wrapped an SkImageGenerator (with an SkImageCacherator stuck in the middle). We could choose to rename either one, but SkImageGenerator is public, so take the easy road and rename the private image subclass. Given the existence of SkImage::isLazyGenerated, this name seems appropriate.

* Change bitmapcache to not rely on lockpixels.Gravatar Mike Reed2017-04-11
| | | | | | | | | | | | | | | | | | | | The Rec in the cache is the owner of the pixel memory - discardable or - malloc Each external client has a pixelref that just points to those pixels, and whose destructor will notify the rec. This eliminates the dependency on lockPixels in pixelref, freeing us to remove that entirely from pixelref.
