+ Follow-up fix to r185766.

+ Reviewed by Zalan Bujtas.
+
+ Suggested by Darin Adler in the bug.
+
+ * platform/graphics/filters/FETile.cpp:
+ (WebCore::FETile::platformApplySoftware): Use WTF::move when passing

+ All calls of ImageBuffer::create should null check the return value
+ https://bugs.webkit.org/show_bug.cgi?id=22132
+
+ Reviewed by Zalan Bujtas.
+
+ ImageBuffer::create returns nullptr for a number of reasons, and should be
+ expected to do so. We missed this check in a few places, resulting in
+ crashes on some systems. Likewise, ImageBuffer::copyImage may return nullptr
+ in normal use and should be checked.
+
+ * platform/graphics/BitmapImage.cpp:
+ (WebCore::BitmapImage::drawPattern): Add nullptr check for create and copyImage. Remove
+ extra call to 'setImageObserver'.
+ * platform/graphics/cairo/ImageBufferCairo.cpp:
+ (WebCore::ImageBuffer::drawPattern): Add nullptr check for copyImage.
+ * platform/graphics/cg/ImageBufferCG.cpp:
+ (WebCore::ImageBuffer::drawPattern): Add nullptr checks for copyImage.
+ * platform/graphics/filters/FETile.cpp:
+ (WebCore::FETile::platformApplySoftware): Add nullptr check for copyImage.
+ * platform/graphics/filters/FilterEffect.cpp:
+ (WebCore::FilterEffect::asImageBuffer): Add nullptr check for create.
+ (WebCore::FilterEffect::openCLImageToImageBuffer): Ditto.
+ * platform/graphics/texmap/BitmapTexture.cpp:
+ (WebCore::BitmapTexture::updateContents): Add nullptr checks for create and copyImage.
+ * svg/graphics/SVGImage.cpp:
+ (WebCore::SVGImage::drawPatternForContainer): Add nullptr check for copyImage.
