This reverts commit d2c2c93cf1.
- Added roll support for Y billboarding
- Fixed a bunch of broken checks that prevented Y billboarding from working properly
- Y billboarding takes precedence over sprite facing
- Optimized ROLLCENTER: now combines the sprite's embedded offsets with SpriteOffsets instead of doing wasteful transforms before/after rotations
- Greatly cleaned up a bunch of cruft
* remove duplicated fields
* make native functions use direct calls
* remove unnecessary pointer from particle_t
* create HWSprite directly in Construct
- Effectively similar to Actors, but without the excess.
- Can be created with either the `level` function or the static `Spawn` function in ZSprite.
- STAT_SPRITE belongs to ZSprites only; ZSprites cannot be moved out of, nor can anything else be moved in to, this statnum.
Misc:
- Fixed (Sprite)Offset taking roll into account.

The Eternity-based definitions are currently disabled due to unclear semantics and overall unsatisfying design. They can be re-enabled once their precise working has been established.
New properties were added to replace them with something that will be clearly specified and is fully ortohonal i.e. they will allow to align an upper tier skew with the floor as well and a lower tier's skew with a ceiling.
* make all legacy light modes except 'Doom' MAPINFO only. A CVAR still exists for testing but its value won't be saved to the config.
* user can only select between "performance', 'software' and 'vanilla'. 'performance' is the old 'Doom' mode which is still needed to speed things up on low end hardware.
* MAPINFO can not enforce any of the two software light modes, as low end users require the option to change this to the 'performance' setting. Selecting one will always revert to the user's light mode selection.
This also adds the `r_actorspriteshadowalpha` and `r_actorspriteshadowfadeheight`
cvars for greater control (only effective in hardware renderers).
These are set to 0.5 and 0 by default, which means this fading behavior
is disabled by default.
When enabled, this has two benefits:
- It becomes easier for the player to judge an entity's height since
the shadow opacity now gives this information.
- Entities that are far high above the ground no longer cast a shadow,
which looked strange.
