This keyword is not expanded by Git which means it's not replaced with the correct revision value in the releases made using git-based scripts and it's confusing to have lines with unexpanded "$Id$" in the released files. As expanding them with Git is not that simple (it could be done with git archive and export-subst attribute) and there are not many benefits in having them in the first place, just remove all these lines. If nothing else, this will make an eventual transition to Git simpler. Closes #14487. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74602 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

// FIXME: Currently, wxScreenDC doesn't work at all in non-exclusive mode
|
|
// (DFSCL_NORMAL). In this mode, requesting primary surface results
|
|
// in one of the following actions, depending on directfbrc
|
|
// configuration:
|
|
//
|
|
// (1) if force-desktop, a surface is created and used as *background*
|
|
// for the windows managed by DFB WM
|
|
//
|
|
// (2) otherwise, a dummy surface of the right size and format is
|
|
// created, but isn't shown on the screen
|
|
//
|
|
// (3) furthermore, if autoflip-window option is not used and primary
|
|
// surface is requested as single-buffered (which is needed to
|
|
// implement wxScreenDC semantics), a warning is issued in addition
|
|
// to 2); if autoflip-window is used, then a helper thread is
|
|
// created and does periodic flipping, which is even worse
|
|
//
|
|
// 2) and 3) are obviously unsatisfactory. 1) isn't suitable either,
|
|
// because wxScreenDC has to render *on top* of windows.
|
|
//
|
|
// In conclusion, wxScreenDC as currently implemented is only usable
|
|
// for measuring things (e.g. font sizes). For this task, however, it
|
|
// is quite expensive to create in DFSCL_NORMAL mode, because it
|
|
// involves creation of a new surface as big as the screen.
|
|
//
|
|
// The surface, as obtained from GetPrimarySurface(), is double-buffered
|
|
// for the sole purpose of silencing the warning from 3) above.
