Update the texture from an image.
*
Although the source image can be smaller than the texture, this function
is usually used for updating the whole texture. The other overload, which
has (x, y) additional arguments, is more convenient for updating a
sub-area of the texture.
*
No additional check is performed on the size of the image, passing an
image bigger than the texture will lead to an undefined behaviour.
*
This function does nothing if the texture was not previously created.
