[RESOLVED] Weird issue with controls position at high DPI

I found that the minimun and maximun limits for the Left position of controls (not tested Top, but it is probably the same) that can be set varies with DPI.

At 200% (192 DPI) the limits are from -114688 to 114681 Twips
At 250% (240 DPI) the limits are from -98304 to 98298 Twips
From 255% (245 DPI) to 300% (288 DPI) the limits are from -81920 to 81915 Twips
From 305% (293 DPI) to 375% (360 DPI) the limits are from -65536 to 65532 Twips
From 380% (365 DPI) to 500% (480 DPI) the limits are from -49152 to 49149 Twips

How to understand these numbers?
