void setImage(Face, Image* image)

Set the texture image for specified face.

inline unsigned int& getModifiedTag(Face face, unsigned int contextID) const

inline void setTextureSize(int width, int height) const

Set the texture width and height. If width or height are zero then the repsective size value is calculated from the source image sizes.

inline void getTextureSize(int& width, int& height) const

Get the texture subload width.

void setSubloadCallback(SubloadCallback* cb)

SubloadCallback* getSubloadCallback()

unsigned int getNumMipmapLevels() const

Get the number of mip map levels the the texture has been created with

virtual void apply(State& state) const

On first apply (unless already compiled), create the minmapped texture and bind it, subsequent apply will simple bind to texture

static Extensions* getExtensions(unsigned int contextID, bool createIfNotInitalized)

Function to call to get the extension of a specified context. If the Exentsion object for that context has not yet been created then and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object only be created with the graphics context associated with ContextID..

static void setExtensions(unsigned int contextID, Extensions* extensions)

setExtensions allows users to override the extensions across graphics contexts. typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
