// RT is 1280x1024 but only contains 512x448 valid data (so 256x224 pixels without upscaling)
//
// PS2 want to read it back as a 1024x1024 pixels (they don't care about the extra pixels)
// So in theory we need to shrink a 2048x2048 RT into a 1024x1024 texture. Obviously the RT is
// too small.
//
// So we will only limit the resize to the available data in RT.
// Therefore we will resize the RT from 1280x1024 to 1280x1024/2048x2048 % of the new texture
// size (which is 1280x1024) (i.e. 800x512)
// From the rendering point of view. UV coordinate will be normalized on the real GS texture size
// This way it can be used on an upscaled texture without extra scaling factor (only requirement is
// to have same proportion)
//
// FIXME: The scaling will create a bad offset. For example if texture coordinate start at 0.5 (pixel 0)
// At 2x it will become 0.5/128 * 256 = 1 (pixel 1)
// I think it is the purpose of the UserHacks_HalfPixelOffset below. However implementation is less
// than ideal.
// 1/ It suppose games have an half pixel offset on texture coordinate which could be wrong
// 2/ It doesn't support rescaling of the RT (tw = 1024)
