Adding -stdlib=libc++ was needed when 10.7 was being targeted because on
10.8 and earlier libstdc++ is the default. Now that the target is 10.9
specifying -stdlib=libc++ is unnecessary since libc++ is the default on
10.9 and later.
Before this fix, tag ranges were adjusted in the json data file, in the 'meta' sector, when the --list-tags and --ignore-empty flags were set.
Particularlly, when --split-layers, --list-tags, and --ignore-empty were on, the calculation of tag ranges could fail with cels with pure mask pixels.
Before this fix, the json file associated with the exported sprite sheet had wrong 'spriteSourceSize' coordinates in particular cases like this:
- Linked cels
- Export Sprite Sheet options: TrimmedCels + Merge Duplicates + SplitLayers checked
Before this fix, a multi-layer mask move (with mixed layer types:
normal layer and tilemap layers with different grids) caused loss of
drawing areas.
The heart of this solution is to correctly align the 'selection mask'
and 'transform data' according to the layer's grid, and also, forcing
'site' TilemapMode/TilesetMode before each
reproduceAllTransformationsWithInnerCmds() iteration.
The scale transformation could have some things to improve in later
commits. Not fully tested yet.
The error is confusing because the user doesn't know that we're trying
to access the clipboard info only to fill Width/Height fields
automatically on File > New. Some errors (like "invalid image format")
should be displayed only when we use Edit > Paste explicitly.
Now we can change several values (zoom, brush size, etc.) pressing a
keyboard shortcuts and dragging the mouse in a specific vector
direction (DragVector). It allows the modification of one, two, or
even more parameters at the same time (e.g. X axis to change the brush
size, Y axis the alpha value of the ink).
It looks like we cannot trust in the get_current_palette() content
when we are running scripts without UI. So it's preferable if we get
the palette directly from the sprite.
We should completely remove the get_current_palette() function.
