* [Lua] Adding Spine atlas parser
* [Corona] Adding ability to load atlas files * [Corona] Added example of using atlas # Documentation: ## Lua runtime: `spine.Atlas.parse` `Atlas.lua` introduces `spine.Atlas.parse(atlasPath, baseDir)` funciton. This function can be use across Lua runtimes to implement their their own image sheet bindings. It will return Array of `Page`s or `nil` if error. ### `Page` properties: * `name` - filename of the page (`"raptor.png"`) * `size` - dimmensions of original image (`[1022,1022]`) * `format` - texture format (`"RGBA8888"`) * `filter` - filter for texture scalin up and down (`["Linear","Linear"]`) * `wrap` - wrap modes (`"none"`) * `regions` - Array of `Region`s on this page ### `Region` properties: * `name` - region name (`"torso"`) * `rotate` - is image rotated in texture (`true`) * `xy` - image frame position on texture (`[610,647]`) * `size` - image frame size on texture (`[54,91]`) * `splits` - (optional) * `pad` - (optional) * `orig` - original image size (`[54,91]`) * `offset` - offset if image was trimmed (`[0,0]`) * `index` - `-1` ## Corona runtime: `spine.GetAtlasSprites` `spine.lua` introduces `spine.GetAtlasSprites(atlasName, baseDir)`, which returns `Sprites` table. This funciton would parse atlas, locate atlas textures, load them to Corona's image sheets and create convinience bindings and functions. User can use convenience functions, or write own wrappers. ### `Sprites` table #### Convenience functions: * `ATLAS_HELPER_createImage` - can be assigned to `skeleton.createImage` * `ATLAS_HELPER_createMesh` - can be assigned to `skeleton.createMesh` * `ATLAS_HELPER_setupSkeleton` - use this on skeleton to assing both creation functions (`sprites.setupSkeleton(skeleton)`) ### Region name bindings: All other elements of `Sprites` table would contain binding `sprites["region_name"] = sheetReference`, where each `sheetReference` contains following elements: * `frame` - number of frame in image sheet (`42`) * `region` - reference to `Region` table * `page` - reference to `Page` table. `Page` table would also get new property - `sheet`, reference to Corona's image sheet where sprites can be accessed. As result, to create image for `attachment` code would look something like `display.newImage( sprites[attachment.name].page.sheet, sprites[attachment.name].frame )`. For more rubust example see `ATLAS_HELPER_createImage` in `spine-corona/spine.lua`. # Known Issues: * Corona would not work with padded/cropped atlases. * Possible (but unprobable) name collision with region names and `ATLAS_HELPER_*` functions.
