Transparent patch support in TEXTURES
Adds transparent patch functionality for the TEXTURES format.
Duplicates source-to-cache column drawer functions and adds extra functionality which uses trans tables.
Changes how the column drawer is picked so it's done once per patch instead of per column.
See merge request !72
* Create a normal skin, but replace the S_SKIN lump with an almost empty one named P_SKIN.
* Provide "name = existing skin name as one of the first line (comments allowed)
* Reset individual spritenames back to zero sprite2s (or one for SPR2_STND to prevent complete removal) via "reset = SPR2_****" statements.
* No support for changing skin properties that are non-visual at the moment, but I don't really feel like it's wise to have those changable with patch alone. (Hello, tons of "modern Sonic" wadfiles which just change vanilla Sonic's ability to CA_HOMINGTHOK!)
* Sprites patch over.
To see an example in action, look at <root>/toaster/smilespatch.wad.
* Set the default flicky group to be equivalent to Flickylist = Demo.
* Refactored a little. (This also removed a crash-causing typo in a Z_Free in P_ClearSingleMapHeaderInfo.)
* MT_EXPLODE's anims partially FF_ANIMATE'd.
* A_FlickySpawn turned into a wrapper for internal function that does what A_FlickySpawn did but returns a pointer to the spawned flicky.
* Added the ability to read in mobjtypes as well as from a short list of flicky constants.
* Added a new state, S_XPLD_FLICKY, which is the new deathstate of all badniks.
* Put the disabled animal-spawn-on-P_KillMobj behind a #define.
* Renamed the branch and associated properties to something not rife with sin.
No idea if this compiles yet (let alone if what is there works at all), just getting this out the way so I can work on certain other things *cough plane displacement cough*
Spindash dust
Charging a spindash kicks up dust, we all know this feature was dying to get in at some point. Bubble and flame forms of spin dust are included from FSonic, for underwater and elemental respectively.
Oh, and as a bonus I reorganised the spindash/spinning/other ability2 stuff code to look a bit neater and more organised.
New resources:
* MT_SPINDUST - the object
* S_SPINDUST1 to 4 - the normal form's states
* S_SPINDUST_BUBBLE1 to 4 - the bubble form's states
* S_SPINDUST_FIRE1 to 4 - the bubble form's states
* SPR_DUST - the normal form's sprite set (uses frames A to D, just pinch FSonic's sprites really)
* SPR_FPRT - the flame form's sprite set (frame A only)
SF_NOSPINDASHDUST disables spindash dust for a character
See merge request !52
* Some shield sounds swapped (can be reverted later).
* Partial implementation of S3K shield abilities.
* The ability to elemental-groundpound onto gold monitors without going straight through them.
* Force shield ability removed because nobody could agree on it, we'll keep it blank until another idea can get through the disagreement juggernaut.
