#311 fixed drawing the flight lines increases main memory usage emca chrfi
Description

to reproduce load several flight lines that will not fit within the given cache. these will load normally with the ram usage being capped at the cache limit. when the image is first drawn the amount of ram being used by the program will increase. This increase seems to be linked to the size of the flight lines. subsequent redraws increase the ram usage slightly but i think this is the same problem being caused by drawing areas that were in cache the first time but now have to be loaded.

once each part of the image has been drawn and loaded out of secondary memory once the increase stops. This at first seems to point to a problem in the caching code and therefore i have used my test bed to perform unit tests on the quadtree and caching classes. These tests showed that without the gui loading and then pulling points out of uncached buckets has no effect on the ram usage of the program.

so far the only theory is that it is caused by an overflow from the graphics card ram.

#326 fixed fence causes colour by height to break emca chrfi
Description

to reproduce, open a flightline, then draw a fence on a smallish area (the bug happens at any size but is more obvious the smaller the area). then go to open and refresh the flight line with the fence selected. When the new area is coloured by height the colours will be incorrect (and the colours will change depending on what controls the brightness)

#327 fixed distance and colour scales emca chrfi
Description

it would be good to add a scale for the distance on screen and the colour by height to lag. prefereably these would be in the main viewing window in one corner floating above the opengl drawn flight line.

they need to be togglable and easy to read against the black background and most of the colours the flightlines can be.
