-    * @param gammaCorrect    Should blur be gamma-correct (sRGB to linear, etc...)
     * @param dstBounds       The destination bounds, relative to the source texture.
     * @param srcBounds       The source bounds, relative to the source texture. If non-null,
     *                        no pixels will be sampled outside of this rectangle.
