Add PortableCompressedTexture
* Resource that allows saving textures embedded in scenes or standalone. * Supports only formats that are portable: Lossy, Lossles or BasisUniversal This is something I wanted to add for a long time. I made it now because @fire requires it for importing GLTF2 files with embedded textures, but also this will allow saving Godot scenes as standalone binary files that will run in all platforms (because textures will load everywhere). This is ideal when you want to distribute individual standalone assets online in games that can be built from Godot scenes.

|

Provides a compressed texture for disk and/or VRAM in a way that is portable.
|
||||
</brief_description>
|
||||
<description>
|
||||
This class allows storing compressed textures as self contained (not imported) resources.
|
||||
For 2D usage (compressed on disk, uncompressed on VRAM), the lossy and lossless modes are recommended. For 3D usage (compressed on VRAM) it depends on the target platform.
|
||||
If you intend to only use desktop, S3TC or BPTC are recommended. For only mobile, ETC2 is recommended.
|
||||
For portable, self contained 3D textures that work on both desktop and mobile, Basis Universal is recommended (although it has a small quality cost and longer compression time as a tradeoff).
|
||||
This resource is intended to be created from code.

Initializes the compressed texture from a base image. The compression mode must be provided.
|
||||
If this image will be used as a normal map, the "normal map" flag is recommended, to ensure optimum quality.
|
||||
If lossy compression is requested, the quality setting can optionally be provided. This maps to Lossy WEBP compression quality.
