Proper image rendering ux (#5)

* can draw from selection

* add light-weight render manager to render many images simultaneously

* [debug me] currently the image close button does not do

* the unselected image can be closed now

* can close images and manually open them on demand

* cosmetic

* image view stuff in render subdirectory

* cosmetic

* generate docs

* review

windows support

some cosmetics
