public class Texture
A Texture wraps a standard OpenGL ES texture.
A Texture can be managed. If the OpenGL context is lost all managed textures get invalidated. This happens when a user switches to another application or receives an incoming call. Managed textures get reloaded automatically.
A Texture has to be bound via the GLTexture.bind()
method in order for it to be applied to geometry. The texture will be
bound to the currently active texture unit specified via GLCommon.glActiveTexture(int)
.
You can draw Pixmap
s to a texture at any time. The changes will be automatically uploaded to texture memory. This is of
course not extremely fast so use it with care. It also only works with unmanaged textures.
A Texture must be disposed when it is no longer used

draw only inside the texture region. Note that this will only draw to mipmap level 0!

AssetManager
. When the context is lost, textures managed by the asset manager are reloaded by the manager
on a separate thread (provided that a suitable AssetLoader
is registered with the manager). Textures not managed by
the AssetManager are reloaded via the usual means on the rendering thread.
