I found the problem and fixed it ^_^
I found that the mismapping was because when i saved the .svg file as an .esp it would force when opened with photoshop the map to become squeezed up, messing up its porportions.
I highly recommend just saving it as .png for anyone else that does it; I tested it and it works perfectly on all sides. I recolored/textured it after getting the proportions fixed and here's the new zone rect along with the new files.
Code:
<ImageStyle Name="exp04_rgn_gorowyn_ph_3room" displayname="Gorowyn Four Room" menugroup="Kunark" zonerect="-42, -40, 45, 61">
<ImageFrame Source="images/maps/map_gorowyn_four_room_1.dds" SourceRect="0,0,436,506" />
</ImageStyle>
and if you do a before and after, you can notice a HUGE difference by switching back and forth.
I'm going to fix the other file as well asap
