With enabled -Woverloaded-virtual gcc warning (see
http://lists.freedesktop.org/archives/libreoffice/2011-March/009567.html),
canvas exposed a nasty clash between WeakComponentImplHelper::disposing
and XEventListener::disposing. Fixed by overriding *once* in baseclass,
and then calling disambiguated, renamed methods.

2005/09/22 21:00:53 thb 1.8.2.4: #i48939# Employing faster XOR masking for the special case nontransparent, non-alpha bitmap redraw in backbuffer (incidently, that matches the typical slide transition sprite update)
2005/07/21 14:52:47 thb 1.8.2.3: #i48939# Factored out round up/down to integer; removed backend specific methods from base Sprite interface; removed updateScreen overwrite from SpriteCanvasBase (too much backend specifics need to be passed to HW canvases); now passing the target OutputDevice directly via Sprite::redraw() method in VCL canvas; made XFont -> impl font conversion dynamic cast, too; removed the getSpriteTargetSurface crap from SpriteCanvas
2005/07/03 20:25:14 thb 1.8.2.2: #i48939# Reworked ParametricPolyPolygon, to extract state in an atomic operation; added more state checking 'isXDirty()' methods to canvascustomspritehelper; added various comments and notes
2005/06/17 23:49:49 thb 1.8.2.1: #i48939# Huge refactoring of canvas; as much functionality as possible is now common in a bunch of shared base classes (input checking, locking, sprite redraw, etc.); added scroll update optimization, transparently to all canvas implementations
2005/04/30 23:56:16 thb 1.7.2.2: #i43238# Largely reworked the update area optimization; now also serving the needs of the RedrawManager to determine whether we can update without backbuffer output preparation; En passant, also fixed a bug that output pos and scale where calculated wrong, if a shape transformation was set but not changed for a sprite redraw
2005/04/26 12:17:24 mbu 1.7.2.1: update area now handled smarter while clip is set
2005/04/12 03:21:23 thb 1.6.2.4: #i44807# Added preliminary version for VCL canvas transformed sprites (taking the slow Set/GetPixel affine transformater from impltools for the time being)
2005/04/11 15:08:47 thb 1.6.2.3: #i36190# Now fully dumped storing of sprite positions (was kinda redundant anyway), because the nominal sprite position has nothing to do with the bound rect's top left edge anymore (due to the transformations); made order of setting/Sprite interface calls more coherent; corrected XSprite::move() semantics (now passes on the bound rect's position and size); changed getSpriteRect() to look similar to dx canvas'
2005/04/08 11:23:23 thb 1.6.2.2: #i36190# Sprite-transform support made it necessary to track update area also for moves (because the sprite size is no longer fixed, but can vary between the enqueuing of the sprite record and the actual repaint; slightly adapted getSpriteRect(), to match bounds actually attained during sprite transform
2005/04/07 10:28:27 thb 1.6.2.1: #i36190# Preparations for full sprite transform support at VCL canvas; safe-guarding against zero-sized sprites; corrected queryTextBounds() to handle baseline offset right.

2005/02/10 04:23:59 thb 1.4.2.2: #i38960# Added opacity detection code, which, according to the drawBitmap() call, determines whether the sprite's content is fully opaque. In that case, we can use the _much_ faster OutputDevice::DrawBitmap() method, instead of the slow mask version

Added classification code to all TODO/HACK/FIXME comments.
There are four categories:
- code quality (C)
- performance (P)
- missing functionality (F)
- and missing/incomplete error handling (E)
Furthermore, every category has a severity number between
1 and 3 associated, where 1 is lowest and 3 highest
severity
