Add options for load Texture2D:

• width
• height
• format
• mipmap

Usage

engine.resourceManager.load<Texture2D>({
  url: '...',
  type: AssetType.Texture2D,
  width: 24,
  height: 24,
  format: ...,
  mipmap: false
})

But additional options can't be inferred by typescript.

now I have to read mesh data back from GPU to assemble texture, this method will cause GLContext lost
