Represents a texture object in Glf.
A texture is typically defined by reading texture image data from an image file but a texture might also represent an attachment of a draw target.

Returns the bindings to use this texture for the shader resource named identifier. If samplerId is specified, the bindings returned will use this samplerId for resources which can be sampled.
Implemented in GlfDrawTarget::Attachment.
GLF_API size_t GlfTexture::GetContentsID | ( | ) | const |
Returns an identifier that can be used to determine when the contents of this texture (i.e. its image data) has changed.
The contents of most textures will be immutable for the lifetime of the texture. However, the contents of the texture attachments of a draw target change when the draw target is updated.
