Transformation settings already applied to the source objects (CGContext, wxWindow) and inherited by wxGraphicsContext should be considered as a baseline transformation matrix for wxGC and shouldn't be exposed through e.g. GetTransform() function (like it's done in Cairo or Direct2D). To report only transformations explicitly applied to wxGC by calls to the corresponding wxGC functions, we need to store initial CTM (in a dedicated variable) and "subtract" it from the actual transformation settings.
See #17609.
Member data containing clipping box have to be updated not only when the clipping region is explicitly changed by SetClippingRegion()/DestroyClippingRegion() but also when existing wxGraphicsContext is associated with wxGCDC using SetGraphicsContext() or when wxGCDC coordinates are transformed with SetDeviceOrigin(), SetLogicalOrigin(), SetUserScale() or SetLogicalScale().
When any of these functions is called then clipping box data are marked as invalid and retrieved from underlying graphics context using wxGraphicsContext::GetClipBox() at nearest call to GetClippingBox().
Solution for wxMSW, wxGTK was implemented in 98714ea452.
See #17646.
If underlying graphics context is rotated then drawing a rectangle with origin at (0,0) doesn't cover all the drawing area. To draw over entire area we need to get extents of the actual clipping region (with applied all transformations) and use it as coordinates of the drawn rectangle.
Solution for wxMSW and wxGTK was implemented in 12eaa61212eaa61930.
See #17636.
A simulation of context menu event by handling directly EVT_RIGHT_UP was implemented in wxSTC in 451c5cc7b9, but later on, EVT_CONTEXT_MENU generation in wxOSX was fixed in 524c47aa3a so simulation is no longer necessary and this event can be directly handled in wxSTC.
This makes it possible to wrap these classes automatically
It also documents wxGIFHandler::SaveAnimation() which wasn't previously
documented at all, even implicitly and so closes#16424.
Closes https://github.com/wxWidgets/wxWidgets/pull/511
Revert one of the changes of 5520702674 which
replaced direct check with a call to lstrlen() which seems to be unneeded and
doesn't compile in non-Unicode build.
