Subject: [PATCH] tiffcrop correctly update buffersize after rotateImage()
fix#520 rotateImage() set up a new buffer and calculates its size
individually. Therefore, seg_buffs[] size needs to be updated accordingly.
Before this fix, the seg_buffs buffer size was calculated with a different
formula than within rotateImage().
Closes #520.

Subject: [PATCH] tiffcrop: Do not reuse input buffer for subsequent images.
Fix issue 527
Reuse of read_buff within loadImage() from previous image is quite unsafe, because other functions (like rotateImage() etc.) reallocate that buffer with different size without updating the local prev_readsize value.
Closes #527
