This change restores the system gallery theme ID to bullets.thm, which
restores language and localization-independent lookup in the gallery UI.
This field was unintentionally removed by a prior update to the file
contents. Updating these .thm files is unnecessarily fragile. There does
not appear to be any way to set an ID other than by using a hex editor,
and the ID field is only retained if updates are incremental. In order
to make this somewhat easier, this change also adds an --id <id>
parameter to gengal. This parameter can be used to manually set the
correct ID when a new .thm file is generated (however, it will not
change the ID for an existing .thm file that is being updated).

Contains graphics related helper code. Lots of the draw and impress code is in this shared library.

xoutdevthis is where a lot of the work would happen to move to the canvas. (what does that mean?)

SdrObject
The shapes you can see in LibreOffice (like rectangle, etc.) are SdrObjects. They are declared as a hierarchy:
SdrObject <- SdrAttrObj <- E3dObject <- E3dCompoundObject <- E3dCubeObj
^ ^ ^ ^ ^ | | ^ ^
| | | | | | | | +--- E3dExtrudeObj
| | | | | | | +----- E3dLatheObj
| | | | | | +------- E3dPolygonObj
| | | | | +--------- E3dSphereObj
| | | | +--- E3dScene...
| | | |
| | | +--- SdrTextObj <- SdrObjCustomShape...
| | | ^ ^ ^ ^ ^
| | | | | | | +--- SdrEdgeObj...
| | | | | | +----- SdrMeasureObj...
| | | | | +------- SdrPathObj...
| | | | +--------- SdrRectObj...
| | | +----------- SdrTableObj...
| | +--- SdrObjGroup...
| + ---- SdrPageObj...
+------- SdrVirtObj...
The above is incomplete of course.
SdrModel / SdrView
Copied from svdview.hxx:
First of all the app creates a SdrModel.
Then it opens a Win and creates a SdrView.
ShowSdrPage() announces a page at SdrView.
It's possible to show SdrView in any Wins at once.
SdrView can show as many Wins as it wants at once. Pages are announced
or checked out with the help of ShowSdrPage()/HideSdrPage(). For every announced
page there is a SdrPageView instance in container aPages. If more than one page
is showed, you have to pay attention that the offset parameter of ShowSdrPage()
is conformed to the size of the page (to prevent overlapping of two pages).
SdrView itself is inherited from many objects in a chain of inheritance (all
that starts with SdrPaintView - that is itself inherited from few classes
too):
SdrPaintView <- SdrSnapView <- SdrMarkView <- SdrEditView <- SdrPolyEditView
^
+----------------------------------------------------------------+
|
SdrGlueEditView <- SdrObjEditView <- SdrExchangeView <- SdrDragView
^
+----------------------------------------------------------------+
|
SdrCreateView <- SdrView
From SdrView on, it is not flat, but a real hierarchy again.

For SdrObjects, there are own DrawingLayer primitives in
svx/source/sdr/primitive2d
The ViewContact / ViewObject / ViewObjectContact are in svx/source/sdr/contact
Decomposes the SdrObjects, and does all sort of operations on them.
If the number of visualizable objects (e.g. SdrObjects) is X, and the number of
SdrViews is Y, then:
- there are
XViewContactinstances (1:1 relation with a visualizable object) - there are
YObjectContactinstances (1:1 relation with anSdrView) - there are
X*YViewObjectContactinstances (1:N relation to both visualizable objects andSdrViews)
