Soup up this comment since it is now separated from its base class ?

// This class manages the conversion of SW-backed bitmaps to GrTextures.
// If the input bitmap is non-volatile the texture is cached using a key created
from the bitmap's unique id and the subset of the texture specified by the
bitmap.

Done.

+class GrBitmapTextureMaker : public GrTextureMaker {

Moved this from SkGr.cpp to here and the corresponding cpp, renamed to be
Gr-prefixed, and updated to take GrContext in its constructor rather than in
overrides to reflect changes to base class.

+public:
+    GrBitmapTextureMaker(GrContext* context, const SkBitmap& bitmap);
+
+protected:
+    GrTexture* refOriginalTexture() override;
+
+    void makeCopyKey(const CopyParams& copyParams, GrUniqueKey* copyKey) override;
+
+    void didCacheCopy(const GrUniqueKey& copyKey) override;
+
+private:
+    const SkBitmap  fBitmap;
+    GrUniqueKey     fOriginalKey;
+
+    typedef GrTextureMaker INHERITED;
+};
