+ * Create a GrBackendTexture from AHardwareBuffer
+ *
+ * @param   context         GPU context
+ * @param   hardwareBuffer  AHB
+ * @param   width           texture width
+ * @param   height          texture height
+ * @param   deleteProc      returns a function that deletes the texture and
+ *                          other GPU resources. Must be invoked on the same
+ *                          thread as MakeBackendTexture
+ * @param   updateProc      returns a function, that needs to be invoked, when
+ *                          AHB buffer content has changed. Must be invoked on
+ *                          the same thread as MakeBackendTexture
+ * @param   imageCtx        returns an opaque image context, that is passed as
+ *                          first argument to deleteProc and updateProc
+ * @param   isProtectedContent if true, GL backend uses EXT_protected_content
+ * @param   backendFormat   backend format, usually created with helper
+ *                          function GetBackendFormat
+ * @param   isRenderable    true if GrBackendTexture can be used as a color
+ *                          attachment
+ * @return                  valid GrBackendTexture object on success
