Abstract base class specifying the required interface for Texture objects.
Texture objects are created via the Renderer. The actual inner workings of any Texture object are dependant upon the Renderer (and underlying API) in use. This base class defines the minimal set of functions that is required for the rest of the system to work. Texture objects are only created through the Renderer object's texture creation functions.
Enumerated type containing the supported pixel formats that can be passed to loadFromMemory.

pure virtual |
Performs an area memory blit to the texture.
sourceData | input data, the size must match area described by the given Rect |
area | area where the blit will happen |
