/**
- * Create fragment program that does a TEX() instruction to get a Z and/or
- * stencil value value, then writes to FRAG_RESULT_DEPTH/FRAG_RESULT_STENCIL.
- * Used for glDrawPixels(GL_DEPTH_COMPONENT / GL_STENCIL_INDEX).
- * Pass fragment color through as-is.
+ * We have a simple glDrawPixels cache to try to optimize the case where the
+ * same image is drawn over and over again. It basically works as follows:
*
- * \return CSO of the fragment shader.
+ * 1. After we construct a texture map with the image and draw it, we do
+ * not discard the texture. We keep it around, plus we note the
+ * glDrawPixels width, height, format, etc. parameters and keep a copy
+ * of the image in a malloc'd buffer.
+ *
+ * 2. On the next glDrawPixels we check if the parameters match the previous
+ * call. If those match, we check if the image matches the previous image
+ * via a memcmp() call. If everything matches, we re-use the previous
+ * texture, thereby avoiding the cost creating a new texture and copying
+ * the image to it.
+ *
+ * The effectiveness of this cache depends upon:
+ * 1. If the memcmp() finds a difference, it happens relatively quickly.
+ Hopefully, not just the last pixels differ!
+ * 2. If the memcmp() finds no difference, doing that check is faster than
+ * creating and loading a texture.
+ *
+ * Notes:
+ * 1. We don't support any pixel unpacking parameters.
+ * 2. We don't try to cache images in Pixel Buffer Objects.
+ * 3. Instead of saving the whole image, perhaps some sort of reliable
+ * checksum function could be used instead.
