The code was refactored moving the BlenderHelper class from "render"
to "doc", and now doc::blend_image() supports blending different color
modes.
Some work is still needed to work with grayscale images correctly.
This refactor includes:
- In Lua now we can clone a custom brush with Brush(Image) and the new
brush doesn't share the image with the original one (added a new test
for this).
- Avoid creating extra images when it's not needed using
Brush::cloneWithExistingImages() (we can inject existing images in
the brush itself).
- Delete Brush-copy contructor & assign operator to use
Brush::clone() functions instead (which are more explicit).
- Some code from 12d8135264 (#4023)
reverted to avoid recreating brushes on left-click or in the brush
preview, i.e. moving the mouse (#4013 refers only to right-click, so
only on right-click we have to adjust the custom brush).
Before this fix to change the main color of the image brush,
it was necessary to choose a new color from the palette.
The secondary color can now also be used.
Also added some tests for image brushes.
Something interesting is that Image:drawPixel() must ask for a rehash
to the tileset when the tile is modified, maybe we can find a better
way to handle this in the future.
Prior to this fix, border padding was clipped to the edge of sprites
on the right and bottom in all export sprite sheet types.
This commit includes tests for 'Export Sprite Sheet' command using
shape padding, border padding, inner padding with 'Packed' sheet type
+ 'Trim Cels' = true.
This patch solves several problems introducing the possibility to
specify a row stride bigger than the width (visible pixels) on each
image row. Useful in case that we want to align the initial pixel
address of each row (if DOC_USE_ALIGNED_PIXELS is defined).
This allows us to use some SIMD intrinsics (e.g. SSE2) for some image
functions in the future (right now implemented only in the new
is_same_image_simd_templ() for is_same_image()).
Anyway to avoid breaking some existing code, by default we'll still
keep the old behavior: row stride bytes = width bytes (so
DOC_USE_ALIGNED_PIXELS is undefined).
New json.decode(jsonText) and json.encode(luaTable) functions.
In this way we don't depend on third-party libraries to decode/encode
JSON text which is a quite common task (in tests and export scripts).
This is the first attempt to finally implement the require() function
on Lua. The main problem was how to solve conflicts between plugins
that use the same library name. Here we separate each plugin like in a
namespace, so require(name) inside a plugin will save the module in
_LOADED["pluginName/libraryName"] to avoid conflicts with other
libraryName from other plugins.
We can use:
Image:clear()
Image:clear(color)
Image:clear(rectangle)
Image:clear(rectangle, color)
If the color is not specified it will be the transparent color of the
image.

* 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
Actually it looks like a long-standing bug in the write/read_tileset()
functions where tileset names aren't saved (so another bug fixed with
this change is that restoring a tileset from a crashes session/file,
will restore the tileset name correctly).
