* improve AssetManager implementation
Notable changes are:
* removed the individual managers inside of d2asset, only one asset manager
* AssetManager now has caches for the types of files it loads
* created a type for TextDictionary (the txt file structs)
* fixed a file path bug in d2loader Source
* fixed a asset stream bug in d2loader Asset
* d2loader.Loader now needs a d2config.Config on creation (for resolving locale files)
* updated the mpq file in d2asset test data, added test case for "sub-directory"
* added a Data method to d2asset.Asset. The data is cached on first full read.
* renamed ArchiveDataStream to DataStream in d2interface
* moved palette utility func out of d2asset and into d2util
* bugfix for MacOS mpq loader issue
* lint fixes, added data caching to filesystem asset
* adding comment for mpq asset close
* Decouple d2asset from d2render
Notable changes in d2common:
* d2dcc.Load now fully decodes the dcc and stores the directions/frames in the dcc struct
* un-exported dcc.decodeDirection, it is only used in d2dcc
* removed font interface from d2interface, we only have one font implementation
* added `Renderer` method to d2interface.Surface, animations use this to bind to a renderer and create surfaces as they need
* added `BindRenderer` method to animation interface
Notable changes in d2common/d2asset:
* **d2asset.NewAssetManager only needs to be passed a d2config.Config**, it is decoupled from d2render
* exported Animation
* Animation implementation binds to the renderer to create surfaces only on the first time it is rendered
* font, dcc, dc6 initialization logic moved out of asset_manager.go
* for dc6 and dcc animations, the process of decoding and creating render surfaces has been broken into different methods
* the d2asset.Font struct now stores font table data for initialization purposes
Notable changes in d2core/d2render:
* Surfaces store a renderer reference, this allows animations to bind to the renderer and create a surface just-in-time
**These last changes should have been a separate PR, sorry.**
Notable changes in d2core/d2ui:
* ui.NewSprite now handles creating an animation internally, only needs image and palette path as arguments
Notable Changes in d2game:
Because of the change in d2ui, all instances of this code pattern...
```golang
animation, err := screen.asset.LoadAnimation(imgPath, palettePath)
sprite, err := screen.ui.NewSprite(animation)
```
... becomes this ...
```golang
sprite, err := screen.ui.NewSprite(imgPath, palettePath)
```
* export d2asset singleton
* add *d2asset.AssetManager to d2app
- d2app now has a reference to an asset manager which it will use for loading
- added asset loader methods to the asset manager
- functions in d2asset are now wrappers for asset manager methods
* add asset manager reference to audio provider
- d2app asset manager reference is now passed to audio provider
- asset manager is created in main.go for now to pass into audio provider
- CreateSoundEffect is now a method, no longer exported, uses the asset manager reference
* d2app passes asset manager refence to map engine test
* in d2asset, all calls to LoadFile replaced with call to Singleton.Loadfile
* blizzard intro and credits screen
- d2app passes reference to the asset manager to these screens
* asset manager for d2map
- adding MapStampFactory, takes an asset manager reference
- embedded MapStampFactory into the MapEngine
- LoadStamp is now a method of the MapStampFactory
* d2asset: removed LoadFileStream, LoadFile, and FileExists
* d2gui changes
- singleton now has an asset manager reference
- calls to d2asset loader functions removed
- createButton is now a method of LayoutManager
- moved LayoutEntry to its own file
* map entity factory
- Map engine has an embedded map entity factory
- Map stamp factory gets a reference to the map engine's entity factory
- Stamps are given a reference to the map engine entity factory when created
- Character select gets a map entity factory
- Embedded the stamp factory into the MapEngine
* asset manager for d2ui
- d2ui is passed an asset manager reference when created
- all calls to d2asset loader functions in d2ui now refer to the asset manager
- d2gamescreen gets a ui manager when created
- help overlay is now passed a ui manager when created
* d2gamescreen + d2player: asset manager references
added an asset manager reference to
- inventory panel + inventory grid
- mini panel
- game controls
- help overlay
- character select
- main menu
- select hero class
- hero stats panel
* Removed d2asset.LoadAnimation
all references to this function have been replaced with calls to the asset manager method
* adding asset to help overlay, bugfix for 4d59c91
* Removed d2asset.LoadFont and d2asset.LoadAnimationWithEffect
all references to these have been replaced with calls to the asset manager methods
* MapRenderer now gets an asset manager reference
* removed d2asset.LoadPalette
all references have been replaced with calls to an asset manager instance
* merged d2object with d2mapentity
d2object was only being used to create objects in the map, so the provider
function is now a method of the map entity factory. calls to d2asset have
been removed.
* removed d2asset.LoadComposite
all calls are now made to the asset manager method
* removed d2asset singleton
all singleton references have been removed, a single instance of the
asset manager is passed around the entire app
* rename Initialize to NewAssetManager
* abstracted palettes, colors, and palette manager
* make asset manager use the palette manager interface
* added BGRA setter/getter, fixed lint errors
* abstraction for animation and animation manager
* abstracted font and font manager
* abstracted palettes, colors, and palette manager
* make asset manager use the palette manager interface
* added BGRA setter/getter, fixed lint errors
* abstraction for animation and animation manager
