Updated: It was added dialog preview support for latest snapshot.
Before you (ggaliens) ask me: yes! I'm using a very small #we (cube) - as you suggested in post #2 (and I already tried before) - and using pst field for carry all data I need to draw it (It's all in memory).
It's really fast than creating a full #we for each update (left using full #we and right using pst+draw OpenGL):

It was used images with this dimensions: 512x512 and 2362x2362 (that is not relevant since they were converted to 384x384)
The code on the github: mv/heightmap_surface_preview

edited the resolution note below of the video.
