Redefine wxTRANSPARENT_WINDOW as 0 and stop using it

Browse source 
This style never did anything useful in wxMSW and did nothing at all in
all the other ports, so always was rather useless, but became actively
harmful not that WS_EX_COMPOSITED is used in wxMSW because using it and
WS_EX_TRANSPARENT, enabled by wxTRANSPARENT_WINDOW, together doesn't
work and results in an endless stream of WM_PAINT messages being sent to
the _siblings_ of the window with wxTRANSPARENT_WINDOW style.

asserts, make sure that wxImageList is created with a valid size before
operating on it.
- wxTRANSPARENT_WINDOW doesn't do anything and shouldn't be used any more. If
you ever used it under MSW (it never did anything in the other ports), you
can turn on the native WS_EX_TRANSPARENT extended style if really needed.
