/* If we are running at the display refresh rate,

* event and carry on.
*
* If we are running at below the display refresh rate,
* then we have problems: frame updates will happen
* entirely out of sync with VBlank0 events. To elaborate,
* we'll wait for a VBlank0 here, but it will already have
* happened partway through the previous frame. So it's:
* 'oh good - let's render the current frame', but the next
* VBlank0 will occur in less time than it takes to draw the
* current frame, resulting in 'overlap' and screen tearing.
*
* This seems to be a consequence of using the GPU directly.
* Other 3DS homebrew typically uses the ctrulib function
* gfxSwapBuffers(), which ensures an immediate buffer
* swap every time, and no tearing. We can't do this:
* instead, we use a variant of the ctrulib function
* gfxSwapBuffersGpu(), which seems to send a notification,
* and the swap happens when it happens...
*
* I don't know how to fix this 'properly' (probably needs
* some low level rewriting, maybe switching to an implementation
* based on citro3d), but I can at least implement a hack/workaround
* that allows 50Hz content to be run without tearing. This involves
* the following:
*
* If content frame rate is more than 10% lower than the 3DS
* display refresh rate, don't wait on the *current* VBlank0
* event (because it is 'tainted'), but instead wait on the
* *next* VBlank0 event (which will ensure we have enough time
* to write/flush the display buffers).
*
* This fixes screen tearing, but it has a significant impact on
* performance...
