Sybren A. Stüvel 2f367db2cc Cleanup: preview rendering, push bContext a bit further down the call stack 
Pass `bContext *C` a bit further down the call stack, to prevent
exploding the number of parameters of `ED_preview_icon_render()`. An
upcoming change will require access to yet another context member, and
this can now be done without adding yet another parameter.

No functional changes.
