Changelog

1.2.0

Water now looks like the game's water: its own colours from the shore to deep sea, reflections of the trees, shore and sky around it, and lighting for the time of day. It used to be a pale grey sheet.
Ambient occlusion: views get the game's soft shading in corners and under foliage (with SSAO on), so they no longer look brighter and flatter than the place itself.
Mistlands: trees, Yggdrasil roots and logs, and anything built of Yggdrasil wood near a portal now appear in the view instead of as a flat picture far behind.
Stepping out of a portal: it already shows its view when the loading screen lifts, instead of opening a few seconds later.

Much less stutter: views are captured under the teleport loading screen instead of while you walk around, and captures are about twice as fast. The first visit to a portal can keep the loading screen up a little longer.
Lighter on the GPU: less work and video memory while you move near portals, especially on the Low and Medium hardware profiles.

Snapshot updates (replaces Capture mode): WhenChanged (default) updates a view when you leave through the portal and something around it was built, removed, grown or dug; EveryTrip updates it on every trip; Once keeps it until frozenportal refresh. Your old choice is carried over.
Preview quality (High / Medium / Low / Auto): how often a view is redrawn as you move. Medium and Low cost less on weaker graphics cards; the picture stays sharp.
One-sided view: show the view only from the side travellers come out of.
Portal hubs: hardware profiles show more views at once (Low 2, Medium 4, High 6, Ultra 8).
Resolution, Max visible portals and Max resident snapshots can now be set one by one on top of any hardware profile (0 follows the profile). Custom is no longer needed; if you used it, your values are kept.

The barrier of a shield generator at your base showed inside portal views.
A wooden portal seen from behind had a gap between the view and the frame.
The inside of ships in a view was filled with the colour of water, and the sea bottom looked dark.
Walking through a portal while its saved view was still loading could leave the old view in place.
Portals that lead to a portal with another name work with XPortal and XPortalNetworks.
Safer after game updates: a change in the game no longer stops every capture or leaves the mod half-working.

Replace the DLL while the game is closed. Settings and saved views carry over; each view is captured once more on your next trip through it (or right away with frozenportal refresh next to the portal).
A new pair of portals shows its views after your first trip through it; two linked portals standing next to each other show them right after linking.

Fixed: textures and surface lighting in portal views could look flat or wrong after restarting the game.
Fixed: portals near each other could flicker between which one shows its view.
Fixed: a closing portal view could disappear before its spiral finished.
Nearby water is now part of the portal view instead of being hidden behind the terrain.
Full-resolution textures are kept, including texture packs (these can use more disk space).
New console command frozenportal log on|off for detailed timings.
Saved scenes from this version cannot be read by older versions of the mod. No cache reset is needed.

Fixed: building ghosts and your own lights no longer appear in portal views.
Fixed: texture-pack changes are picked up correctly by new captures.
Fixed: some flickering and mismatched lighting while a portal view was being rebuilt.
Lower memory use while saving a capture.
Capturing during teleport waits for a fully black screen and gives up after three seconds, keeping the old view.
Use frozenportal refresh next to a portal to remove ghosts or lights already baked into an older view.

The distant landscape and clouds behind a portal view are twice as sharp on the High and Ultra hardware profiles and no longer shimmer from afar.
New setting Panorama resolution (0 = by hardware profile, 512, 1024 or 2048). Higher values are sharper but make each capture longer and use more video memory.
Existing views keep their panorama until the portal is captured again.
