* Fix some wipe bugs.
	* Solved that thing where there was no fade between two back-to-back cutscenes.
	* Fixed there being no effective wipe between the end of the vanilla intro cutscene and the title screen.
	* Smoothed out the behaviour of titlemap fades to prevent conflicts.
* [COMPLETELY UNRELATED] Kill the pause graphic and replace with a blue box with text in it, like what happens when the window loses focus. Much harder to miss.

* Now reads "HOLD TO RETRY...".
* Behind the white flash.
* Shows on button tap for about half a second.

* Obligatory GIF: https://cdn.discordapp.com/attachments/400761370800422922/456586705424875520/srb20047.gif
* Show powerup display in singleplayer even while holding Game Status button.

* Do not subtract a life when retrying if you have infinite lives.

OpenGL: Paper Sprites: The Thousands of Bugs

basically we don't want L/R sprites to always be flipped, for obvious reasons

(Seperate AL and AR sprites were broken, I figured out I was a dunce, oh noey)

This should hopefully kill the F12 getting stuck issue once and for all.

Move old fix for too large maps having rendering issues from R_CheckBBox to OpenGL's HWR_CheckBBox
From what I know, this effects at least Aerial Garden and Seraphic Skylands

Stop Each Time trigger linedefs and object-carrying scrollers from doing anything with FOFs without FF_EXISTS

The FixedMul() C implementation would produce off by one results,
causing constant desyncs on 64 bit builds and builds without an
ASM implementation of the function.

This is fixed by shifting instead of dividing, possibly avoiding
rounding errors.

This makes OpenGL stop using a specific function that doesn't really do anything for it anymore. It looks like it was used for a hack that would change the colour of polygons for the flashpal equivalent in DOOM.
I made it so ST_DoPaletteStuff doesn't set the flashpal in OpenGL as it already does its own hacky overlay and doing that would cause all the textures to be flushed more mid-level, it could be enabled for more correct flashpals, but they still wouldn't effect fog or lighting.
This means the palette will be set when going to the title screen, and twice when starting a map, (causing the OpenGL cached textures to also be flushed at those times)

Change to linedef type 7 (flat alignment): If no tag is given, affect front sector.

See merge request STJr/SRB2Internal!145

Also move the Bouncy FOF sector special check above the FOF heights checking in P_CheckBouncySectors, because it means not having to waste time calculating FOF heights only for it not to be bouncy anyway :P
