4     When a process is created, DbgInitDebugChannels will locate DEBUGCHANNEL
5     environment variable and extract information about debug channels.
6     This information includes which of the win32k debug channels will be
7     enabled for the current process and which level of a channel will be active.
8     This information will be stored in ppi->DbgChannelLevel.
9     In this way user mode can control how win32k debugging will work when
10     the following macros are used: ERR, FIXME, WARN, TRACE
11 
12     By default only the ERR channel will be active. Remember that other
13     debug channels can be activated for applications that are executed with a DEBUGCHANNEL
14 
15     Valid syntax for DEBUGCHANNEL is the following:
16     +UserProcess,info+UserWnd,err+UserWndpos,-listview
17     warn+UserMsgQ,-UserMsgGet,+shell
18 
19     Note the following:
20     The debug level is not required
21     The operation to enable/disable (+/-) and the name of the channel is required
22     Channels are devided by commas
23     No spaces are allowed
24     The syntax is case sensitive. Levels must be lowercase and
25     the names of the channels must be exactly like they are defined in DBG_DEFAULT_CHANNEL
26     This syntax can be mixed with wine debug channels without problems
