? wads: register wad format, mount wads, load map, unmount wads, unregister format (may be, register globally ?)
!! FIX brush creation, do not DropError() from MapBrush.cpp module
- 'ahl_streets': lamps have 'halo' with rendermode==5 (additive)
- 'ccity2':
  - have rotating lamps with rendermode=5 (additive)
  - BUG: this rotating lamp have surf with "red" texture, which is listed in "lights.rad" -- it will generate light
    emitter at map position {0,0,0}
  - have sliding doors with glasses -- uses trigger_multiple for synch ?
! use LightOrigin for renderer entity (weapon model, multi-part models ...)
! HL: map "bxnwo1" using "+atexture" on windows ("alternative animation") -- currently, incorrectly used in engine!
  (entity can be switched on and off, with a different animations; not used on static objects?)

! HL/KP: have maps with "PF_setmodel NULL" error
- inline bool CBrush::IsEmpty(); use in cmodel.cpp, no errors in MapBrush.cpp
- hl: aaatrigger -- invisible texture ? (check: may be, have in wads?)

- Q1 sky (not HL!): should occlude other map surfaces (check: map "a2", "kasteel")
- CS_NAME (map message) with bad chars:
  ? check 7th bit for each char, replace with color
  ! server: do not colorize string for old clients
  * may be, process "worldspawn::message" param in EntityParser.cpp -- easier, more generic
  - NOTE: CS_NAME may be too long to transfer via configstrings[MAX_QPATH==64]
  - example map with long message: "q1/efdm10"

- texture loading:
  - should delete all textures (map textures) on next map loading, because:
    - q1: embedded textures: should delete all on map change (different maps -- may be different textures
      with the same name)
    - hl: wad textures: different maps => different wads ...
    ? may be, delete textures for Q2/Q3 maps too -- fast enough to reload them
    ! should delete textures and shaders!
    ! should check: main engine can use shaders by 'handle' (pointer) -- this will require to not delete these shaders, or
      refresh pointers after map restart/change; may be, use 'smart pointers' with garbage collection

- check player trace bounds + viewheight for q1/hl (q1: looks like same as q2; hl -- needs scaling?!)
- q1/hl: check lightstyle strings
	// HL: added
	// 12 UNDERWATER LIGHT MUTATION
	// this light only distorts the lightmap - no contribution
	// is made to the brightness of affected surfaces
	LIGHT_STYLE(12, "mmnnmmnnnmmnn");
? FORCE ext protocol for clients, when playing q1/hl map (not required: original q2 will fail to load these maps anyway)

- boot_camp (and other HL mas): lots of func_illusionary, which should clip player movement -- because clip created for
  hulls #2 and #3, and not created for hull #1 (which we are use)

- check HL animMap.freq (HL viewer: 10 Hz; Q1 - 5 Hz; Q2 - 2 Hz) -- disassemble ...

------------ hl entities ---------------
- func_button: incorrect movement angle, speed (?)
- func_breakable: replace with func_explosive; may require additional target_speaker with explosion sound
  - KP: func_explosive on "japan" - windows with explosion (check game code ?)
- lifts does not works! ("ccity2", "bxht")
- sounds does not works
- door sounds (create linked trigger with sound? -- check entity count overflow!)

--------------- later ------------------
* hl: "lights.rad" file (SURF_LIGHT analog)
? hl: water waves
? ents: convert q1 NPC to q2 NPC
- surface sounds (hl) -- requires surface info in Trace()
- ambient sounds (see dBsp1Leaf_t)
- .mdl models for Q1 (torch etc)
- func_illusionary: can have "skin" field -- used as contents (default == -1 == Q1_CONTENTS_EMPTY); may be used to
  create water etc (work PointContents() only ? SOLID_NOT is set by game (q1/hl) for func_illusionary)
- HL: "infodecal" entities (and check AHL map "bxht")
- HL: "-0texture" - randomly tiled (using all available "-1texture" etc)
- "lights.rad": currently, color is ignored!
  - can detect light surfaces:
    1) check lightmap for all faces with same texture
    2) all of them should be filled with a single color (because received light is smaller, than emitting light)
    3) at least one of color components should be 255 (normalized color)
