- * 3) One to be currently held by the X server
- * 4) One to render to
+ /* For IMMEDIATE and FIFO, most games work in a pipelined manner where the

+ * the render latency is CPU duration + GPU duration.
+ *
+ * This means that with scanout from pageflipping we need 3 frames to run

+ * 1) CPU rendering work
+ * 2) GPU rendering work
+ * 3) scanout
+ *
+ * Once we have a nonblocking acquire that returns a semaphore we can merge
+ * 1 and 3. Hence the ideal implementation needs only 2 images, but games
+ * cannot tellwe currently do not have an ideal implementation and that
+ * hence they need to allocate 3 images. So let us do it for them.
+ *
+ * This is a tradeoff as it uses more memory than needed for non-fullscreen
