+ * Section 4.3.2(Reading and Copying Pixels) From GL spec 3.2 core:
+ * If the read framebuffer is layered (see section 4.4.7), pixel values are

+ * written to layer zero. If both read and draw framebuffers are layered, the
+ * blit operation is still performed only on layer zero.
+ *
+ * Test Layout
+ * *-------*-------* test1:
+ * | | | Source tex is layered, destination tex is layered
+ * | test3 | test4 | test2:
+ * | | | Source tex is layered, destination tex is not layered
+ * *-------*-------* test3:
+ * | | | Source tex is not layered, destination tex is layered
