+#Class SkImage
+
+SkImage is an abstraction for drawing a rectangle of pixels, though the
+particular type of image could be actually storing its data on the GPU, or
+as drawing commands (picture or PDF or otherwise), ready to be played back
+into another canvas.
+The content of SkImage is always immutable, though the actual storage may
+change, if for example that image can be re-created via encoded data or
+other means.
+SkImage always has a non-zero dimensions. If there is a request to create a new
+image, either directly or via SkSurface, and either of the requested dimensions
+are zero, then nullptr will be returned.

+
+This method allows clients to capture the data necessary to turn a SkImage into a texture-
+backed image. If the original image is codec-backed this will decode into a format optimized
+for the context represented by the proxy. This method is thread safe with respect to the
+GrContext whence the proxy came. Clients allocate and manage the storage of the deferred
+texture data and control its lifetime. No cleanup is required, thus it is safe to simply free
+the memory out from under the data.
+
+The same method is used both for getting the size necessary for uploading
+and retrieving texture data. The deferredTextureImageUsageParams array represents the set of
+draws over which to optimize the texture data prior to uploading.
+
+When called with a null buffer this returns the size that the client must allocate in order
+to create deferred texture data for this image (or zero if this is an inappropriate
+candidate). The buffer allocated by the client should be 8 byte aligned.
+When buffer is not null this fills in the deferred texture data for this image in the
+provided buffer (assuming this is an appropriate candidate image and the buffer is
+appropriately aligned). Upon success the size written is returned, otherwise 0.
+dstColorSpace is the color space of the surface where this texture will ultimately be used.
+If the method determines that Mip_Maps are needed, this helps determine the correct strategy
+for building them (gamma-correct or not).
+
+dstColorType is the color type of the surface where this texture will ultimately be used.
+This determines the format with which the image will be uploaded to the GPU. If dstColorType
+does not support color spaces (low bit depth types such as kARGB_4444_SkColorType), then dstColorSpace
+must be null.
