By default Aseprite will not try to match flipped versions of the
tiles (as it requires more CPU), but when we create a tileset we can
specify which flips can be matched automatically (new
Tileset::matchFlags() property).
These flags are just for the Auto mode, if we manually insert a
flipped tile, that is always supported, even when the matchFlags() are
not specified.
* Changed the "90cw" flag to "diagonal flip" (the tile should be
rendered with X/Y axis switched in this case)
* Each time we read/write an .aseprite file we have to convert
the mask/shift from the file to the values expected in
memory (tile_f_xflip/yflip/dflip)
* Now a Cel has a z-index property to change the order of layers per frame
* A new doc::RenderPlan class can calculate the order of cels to be rendered
* z-index is saved as a int16_t in the .aseprite files
* This new field can be set/get from Lua with Cel.zIndex
Added a Sprite.tileManagementPlugin property for plugins that want to
replace the standard tilemap/tileset interface. This includes a new
external file field in .aseprite files to specify that the sprite
tiles are controlled by a specific plugin.
Once this property is set, the standard tilemap/tileset modes
selectors will disappear and the only way to make then available will
be setting this property to nil/empty string again.
Fix https://github.com/aseprite/Attachment-System/issues/21
Don't use GitHub tables for the spec, they don't work for this kind of
documents. I've restored the old layout using just plain text to
describe chunks and fields.
Changes:
* Added SeparatorInView() to add separators inside a ListBox or ComboBox.
* Added BlendModeItem() to represent each item in the blending modes
ComboBox.
* Now a ComboBox can contain any kind of widgets as children (not just
ListItem). This is required to add separators in the blending modes
ComboBox.
