Summary	0022912: After calling AIS_InteractiveContext::UnsetColor objects are drawn with the same color when transparency is changed
Description	After unsetting the color of some interactive objects and setting new colors, all these objects are drawn with the same color when their transparency is changed. In our application, the same problem occured when the number of iso lines of the context is changed (via AIS_InteractiveContext::SetIsoNumber) instead of the transparency. It seems that the shapes use the default drawer in some cases after unsetting the color. But this is only my impression as a user, I didn't debug the code.
Steps To Reproduce	To reproduce the problem you can use the following Draw commands: restore p.brep p explode p vinit vdisplay p_1 vdisplay p_2 vfit vsetdispmode p_1 1 vsetdispmode p_2 1 vsetcolor p_1 red vsetcolor p_2 green vunsetcolor p_1 vunsetcolor p_2 vsetcolor p_1 red vsetcolor p_2 green vsettransparency p_1 0.5 vsettransparency p_1 0
