Added the auto-conversion of images to InsetGraphics, this adds support for bitmap images. Modified the mechanism of image loading for inline viewing - still not working though. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@1457 a592a061-630c-0410-9148-cb99ea01b6c8

/* (Baruch Even 2000-08-05)
|
|
* This has a major drawback: it is only designed for X servers, no easy
|
|
* porting to non X-server based platform is offered right now, this is done
|
|
* in order to get a first version out of the door.
|
|
*
|
|
* Later versions should consider how to do this with more platform
|
|
* independence, this will probably involve changing the Painter class too.
