vb25 bug: Image Aspect Lock

[tinmanjuggernaut]

Andrey, when "Image Aspect Lock" is turned in it causes my cpu to spike. Digging into it I found when it is locked, it causes the whole panel to be continuously redrawn for some reason, causing constant cpu usage. I couldn't find the source of the problem.

Also VRayScene.image_aspect min and soft_min should be 0.1. On a casual scrolling of image aspect ratio, if you hit zero, that subpanel dies due to div by zero.

Re: vb25 bug: Image Aspect Lock

tinmanjuggernaut, this some kind of experiment and it also works only in a "special build" because generally any params assignment in deprecated in draw() function (in UI). And btw cpu load is find for me...

Re: vb25 bug: Image Aspect Lock

I'm running win 7/64. If I use either my 64-bit build 2.56 r34630, or your 32-bit build 2.55 33895 and updating the script with "git pull", I see the same results.

By opening blender and clicking "image aspect lock" it continually calls the draw function (VRAY_RENDER_dimensions->draw, among others) and the cpu spikes. However, if I turn off the render panel by switching to material or texture, cpu goes back to normal. It's only when the render panel is on screen and image aspect lock is checked that it continually draws that whole panel. If you put a print statement in that function, you should see it dumping lines to the console continuously when that box is checked, rather than just when it needs to redraw.

Ok. It's really low priority. We can set it manually. I just wanted to give you the information.
Thanks!
