For some engines such as Dreamweb that a previous fix did not apply
to, this fixes bug 6996: Android: Mouse pointer control with
analog joystick is unusable
As the virtual keyboard trigger has been moved to CTRL-F7, the previous
code which generates a unmodified F7 event to do this will not work.
Rather than just adding the CTRL modifier, this code changes the
backend to directly generate the virtual keyboard trigger event
directly. This avoids any future breakage if the key combination is
changed again.
This gets rid of the hacks, where SdlEventSource added events with custom type
numbers to pass SDL_VIDEOEXPOSE and SDL_VIDEORESIZE to the graphics manager.
Furthermore it get rids of the uninituitive and hard to trace way of assigning
the proper mouse coordinates to mouse related events. Formerly it passed the
real screen coordinates through the even dispatching api to the graphics
manager (at least hopefully ;-) and let that handle creating a new event with
the proper coordinates. Now instead SdlEventSource handles the proper
coordinate setup itself.
Since this is a behavior change and I can not test all the SDL based small
devices ports this commit might break compilation for them and more serve it
might also break mouse position behavior. If any of that occurs I am sorry
about it.
It seems in the gsoc2010-opengl branch, the dingux port was not anymore
updated at some point, so some changes that were made in general did not
make it till here. This is my attempt to fix at least the most obvious
problems, but without being able to compile it, all these changes should
be very carefully reviewed.
