Fields§
§graphic_map: HashMap<Id, Graphic>
§next_id: u32
Next id to use when a new graphic is added
atlases: Vec<(SimpleAtlasAllocator, usize)>
Atlases with the index of their texture in the textures slab.
textures: Slab<(Arc<Texture>, UiTextureBindGroup, UiUploadBatchId)>
Third tuple element is a list of pending premultiply + upload operations for this frame. The purpose of this is to collect all the operations together so that a single renderpass is performed for each target texture.
cache_map: HashMap<CacheKey, CachedDetails>
The location and details of graphics cached on the GPU.
Graphic::Voxel images include the dimensions they were rasterized at in the key. Other images are scaled as part of sampling them on the GPU.
keyed_jobs: KeyedJobs<CacheKey, RgbaImage>

Source rectangle should be from 0 to 1, and represents a bounding box for the source image of the graphic.
Panics
Panics if one of the lengths in requested_dims is zero.
