Textures may be packed incorrect when resampled in `Bilinear` or `Nearest` with some scale values #745

Description: When packing textures, if Bilinear or Nearest is set in the Resample option, some scale values pack the images incorrectly. For example, if the scale value is set to 0.49, the image will look as if part of the image is duplicated, as shown in the blue boxed area of the following image:

spineboy-pro_Bilinear_Scale-049

Expected behavior: It should correctly look like the following:

spineboy-pro_Bilinear_Scale-050

Steps to reproduce:

  1. Open "spineboy-pro.spine".
  2. Open the Texture Packer window, set Input folder to Spineboy's images folder, and click the Pack Settings button.
  3. Set Scale to 0.49 and Resample to Bilinear.
  4. Run the texture pack and check the texture atlas page in the output folder.

Also, if you try with a scale value of 0.5 or 0.48, you can confirm that this problem does not occur.
