libretroadmin 51d238875e Get rid of obsolete HAVE_VIDEO_LAYOUT - obsolete spec, was only 
ever implemented for OpenGL2 driver, lots of code debt, best to
instead just keep improving the overlay system instead which is
already available for most video drivers

*
* 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...
