We were incorrectly saving a wrong number of entries for palettes with
more than 256 colors in color2 chunk, anyway it doesn't make sense to
use this chunks as it doesn't support more than 256 colors. So we
removed it for this case.
We've also removed the palette chunk for cases where it's not required
at all, e.g. when we have less than 256 colors and doesn't have alpha
channel, it makes sense to use the color2 chunk as it's smaller in the
output file.
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.
