// For an out of bounds copy, we must ensure that the copy wraps to the next line,
// so for a copy from a 64x64 texture, in the region [32, 96[, there are 32 pixels that are
// outside the bounds of the texture. We fill the destination with the first 32 pixels
// of the next line on the source texture.
// This can be emulated with 2 copies (the first copy handles the region inside the bounds,
// the second handles the region outside of the bounds).
// We must also extend the source texture by one line to ensure we can wrap on the last line.
// This is required by the (guest) OpenGL driver.
