-/**
- * The GL_EXT_framebuffer_object allows the user to create their own
- * framebuffer objects consisting of color renderbuffers (0 or more),
- * depth renderbuffers (0 or 1) and stencil renderbuffers (0 or 1).
- *
- * The spec considers depth and stencil renderbuffers to be totally independent
- * buffers. In reality, most graphics hardware today uses a combined
- * depth+stencil buffer (one 32-bit pixel = 24 bits of Z + 8 bits of stencil).
- *
- * This causes difficulty because the user may create some number of depth
- * renderbuffers and some number of stencil renderbuffers and bind them
- * together in framebuffers in any combination.
- *
- * This code manages all that.
- *
- * 1. Depth renderbuffers are always allocated in hardware as 32bpp
- * GL_DEPTH24_STENCIL8 buffers.
- *
- * 2. Stencil renderbuffers are initially allocated in software as 8bpp
- * GL_STENCIL_INDEX8 buffers.
- *
- * 3. Depth and Stencil renderbuffers use the PairedStencil and PairedDepth
- * fields (respectively) to indicate if the buffer's currently paired
- * with another stencil or depth buffer (respectively).
- *
- * 4. When a depth and stencil buffer are initially both attached to the
- * current framebuffer, we merge the stencil buffer values into the
- * depth buffer (really a depth+stencil buffer). The then hardware uses
- * the combined buffer.
- *
- * 5. Whenever a depth or stencil buffer is reallocated (with
- * glRenderbufferStorage) we undo the pairing and copy the stencil values
- * from the combined depth/stencil buffer back to the stencil-only buffer.
- *
- * 6. We also undo the pairing when we find a change in buffer bindings.
- *
- * 7. If a framebuffer is only using a depth renderbuffer (no stencil), we
- * just use the combined depth/stencil buffer and ignore the stencil values.
- *
- * 8. If a framebuffer is only using a stencil renderbuffer (no depth) we have
- * to promote the 8bpp software stencil buffer to a 32bpp hardware
- * depth+stencil buffer.

+/**
+ * The GL_EXT_framebuffer_object allows the user to create their own
+ * framebuffer objects consisting of color renderbuffers (0 or more),
+ * depth renderbuffers (0 or 1) and stencil renderbuffers (0 or 1).
+ *
+ * The spec considers depth and stencil renderbuffers to be totally independent
+ * buffers. In reality, most graphics hardware today uses a combined
+ * depth+stencil buffer (one 32-bit pixel = 24 bits of Z + 8 bits of stencil).
+ *
+ * This causes difficulty because the user may create some number of depth
+ * renderbuffers and some number of stencil renderbuffers and bind them
+ * together in framebuffers in any combination.
+ *
+ * This code manages all that.
+ *
+ * 1. Depth renderbuffers are always allocated in hardware as 32bpp
+ * GL_DEPTH24_STENCIL8 buffers.
+ *
+ * 2. Stencil renderbuffers are initially allocated in software as 8bpp
+ * GL_STENCIL_INDEX8 buffers.
+ *
+ * 3. Depth and Stencil renderbuffers use the PairedStencil and PairedDepth
+ * fields (respectively) to indicate if the buffer's currently paired
+ * with another stencil or depth buffer (respectively).
+ *
+ * 4. When a depth and stencil buffer are initially both attached to the
+ * current framebuffer, we merge the stencil buffer values into the
+ * depth buffer (really a depth+stencil buffer). The then hardware uses
+ * the combined buffer.
+ *
+ * 5. Whenever a depth or stencil buffer is reallocated (with
+ * glRenderbufferStorage) we undo the pairing and copy the stencil values
+ * from the combined depth/stencil buffer back to the stencil-only buffer.
+ *
+ * 6. We also undo the pairing when we find a change in buffer bindings.
+ *
+ * 7. If a framebuffer is only using a depth renderbuffer (no stencil), we
+ * just use the combined depth/stencil buffer and ignore the stencil values.
+ *
+ * 8. If a framebuffer is only using a stencil renderbuffer (no depth) we have
+ * to promote the 8bpp software stencil buffer to a 32bpp hardware
+ * depth+stencil buffer.
