' Load texture

	' Attempt To load image
	Local TextureImage:TPixmap=LoadPixmap(URL);
	
	' Save dimensions for later
	Self.Width=TextureImage.Width
	Self.Height=TextureImage.Height
	
	' Create GL texture
	glGenTextures 1, Varptr TexID
	
	' Bind it first
	Bind()

	' Enable bilinear filtering
	glTexParameteri GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR
	glTexParameteri GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR
	
	' Create actual texture
