Unable to render after shiny validate

[dipterix]

When used in shiny, there is a chance that the viewer does not render correctly:

This happens in when following the following steps

1. In renderBrain function, use shiny validate to raise errors when 3D model is missing
2. then load a RAVE subject with no 3D model
3. load another subject with 3D model

The issue was caused by widget dimension become 0px x 0px after resizing in R-shiny app, which is not the issue of threeBrain.

However, what threeBrain can do is to delay resizing when detecting canvas size being too small, and only resize when canvas size is large enough (> 10px on each side)
