Description
This is hrev54051.
Setting background color of parent view in AttachedToWindow is often used because BeOS don't support transparent views. With hrev53713, hrev54051 transparent views support was introduced in Haiku and this workaround is no longer needed. For making transparent view, its need to set B_TRANSPARENT_BACKGROUND view flag and set view color to B_TRANSPARENT_COLOR.
Note:
See TracTickets
for help on using tickets.
Note that using transparent views don't have efficiency issues, it is even more efficient because clipping is simplified and more sequential memory access is used. Views are not rendered in parallel because there are only 1 thread per window.
