Attached animation draw offset customizations

[Starkku]

Draw offset customization

• YDrawOffset.ApplyBracketHeight makes Y axis position follow it's owner object's selection bracket height (for buildings, this is based on Height and Foundation, for others it is influenced by PixelSelectionBracketDelta) if it is attached to one.
  • By default this will only apply if the bracket position is negative e.g it is moved upwards from the object center. If YDrawOffset.InvertBracketShift is set to true, the opposite is true and negative shift is ignored.
  • The bracket-based shift can be further adjusted with offset from YDrawOffset.BracketAdjust, overridden by YDrawOffset.BracketAdjust.Buildings for buildings only.

In artmd.ini:

[SOMEANIM]                            ; AnimationType
YDrawOffset.ApplyBracketHeight=false  ; boolean
YDrawOffset.InvertBracketShift=false  ; boolean
YDrawOffset.BracketAdjust=0,0         ; X,Y, pixels relative to default
YDrawOffset.BracketAdjust.Buildings=  ; X,Y, pixels relative to default

AttachEffect animation-specific

• Animation.DrawOffsetN (where N is integer starting from 0) can be used to define draw offset rules for the animation. These are parsed starting from index 0 until offset with value 0,0 is encountered.
  • Animation.DrawOffsetN.RequiredTypes contains list other AttachEffectTypes that need to be attached on the same techno as the current one for the draw offset rule to apply.

In rulesmd.ini:

[SOMEATTACHEFFECT]                                 ; AttachEffectType
Animation.DrawOffsetN=0,0                          ; X,Y, pixels relative to default
Animation.DrawOffsetN.RequiredTypes=               ; List of AttachEffectTypes

Going to merge this in 24h since there is no other person willing to test it.
