- Changes in libAfterImage (draw.c & draw.h), TASImage.cxx
and TImageDump.cxx in order to produce nice looking
circular (hollow and solid) markers. Previously the line
used to draw hollow circular markers looked very thick and
the solid ones did not look circular.

- From Onuchin:
In batch, when a picture was saved in a binary file (gif for instance) from
an image containing more than one pad, only the first pad was saved. The
following macro demonstrates the problem: ccc2.gif was wrong compared to
ccc1.gif.
{
gROOT->SetBatch();
TCanvas *c = new TCanvas;
c->Divide(1,2);
TH1F *h = new TH1F("gaus", "gaus", 100, -5, 5);
h->FillRandom("gaus", 10000);
c->cd(1); h->Draw();
c->cd(2); h->Draw("c*");
c->Print("ccc1.gif");
TImage *img = TImage::Create();
img->FromPad(c);
img->WriteImage("ccc2.gif");
}

From Valeriy Onuchin:
- add possibility to create an animated GIF file from canvas
(in both GUI and batch mode).
It's possible to Print pad into an animated GIF file by specifying
the file name as "myfile.gif+" or "myfile.gif+NN" ,
where NN is the delay for displaying subimages during animation in 10ms units.
If NN is ommitted the delay between subimages is zero.
for (int i=0; i<10; ++i) {
// fill canvas for context
// ...
c1.Print("file.gif+"); // print canvas to GIF file
}// end loop

From Valeriy O.
- libAfterImage.tar.gz
Fixes for few bugs in reading multi-image gif files by
Sasha Vasko and Valeriy Onuchin
- TASImage.cxx
o Several image formats can support subimages e.g.
GIF, TIFF, BMP, XCF, ICO etc. The famous ones are
animated GIF files.
Possiblity to read subimages from multi-image files added.
For example,
i1 = TImage::Open("anim.gif.0"); // read the first subimage
i2 = TImage::Open("anim.gif.1"); // read the second subimage
i4 = TImage::Open("anim.gif.3"); // read the forth subimage
o TASImage::Draw method. Take into account the
gStyle->GetScreenFactor() when a new canvas displaing an image is created.
- TImageDump.cxx
o Small correction in comment

From Christian Holm:
* Fixes to SapDB plugin to allow compilation on AMD64.
* Fixes to ODBC plugin to allow compilation on AMD64.
* Fix TTF to also use new `symbol.ttf' font when using free fonts.
* Fix to TImageDump to use free `symbol.ttf'
* The recent change to PROOF client side to not use plug-ins(!?)
forgot to include the header `config.h' in case `HAVE_CONFIG' is
defined. That meant, that ROOTLIBDIR was _never_ defined there,
and so the libraries could not be found on a `static'
installation.
* Update of copyright for root-common package due to new symbol.ttf font.
* Remove old packaging files that clutter the directory and may cause harm.
* Wording corrections for package description.
* Fixes to some dependencies.
* Fix to TTF installer package to not overwrite symbol.ttf.
* Some fixes to package preparation scripts.
* Remove some files in `make distclean' left over after build.
* Added package `root-plugin-odbc'.

From Valeriy:
TGPicture:
- fix deallocation autogenerated disabled pictures. That allows to fix
seg. violation after running $ROOTSYS/test/stress reported by Markus Frank.
An important comment was added to constructor
TGPicture(const char *name, Pixmap_t pxmap, Pixmap_t mask)
"both pixmaps pxmap and mask must be unique (not shared)"
- new method TGPicturePool::GetPicture(const char *name, char **xpm) added
that allows to create pictures from in-memory XPM array
Example:
#include "myicon.xpm" // contains static char** myicon {..} array
const TGPicture *pic = gClient->GetPicturePool()->GetPicture("myicon",
myicon);
TGButton:
- new method SetEnablled added which allows to activate/deactivate
enabled/disabled state of button
TASImage/TImage:
- Few new vector graphics methods added:
DrawCubeBezier, DrawStraightEllips, DrawCircle, DrawEllips,DrawEllips2
ToGray method, which allows to convert RGB image to Gray image
TImageDump:
- open circle polymarkers are implemented

From Valeriy Onuchin:
1. TVirtualPS - 3 "abstract" methods added
void *GetStream() const
returns pointer to "backend", which is file stream for
TPostScript, TPDF, TSVG classes, and is TImage object for TImageDump
class.
void SetType(Int_t) , GetType() const
setter/getter methods
2. TImageDump
If type is 114 - do not write to file on delete or Close()
3. TASImage
- more 10-20% gain achived in drawing speed
- fix problems in painting image in batch mode, e.g.
$root -b
root[] .x rose_image.C
root[] c1->Print("c1.png")

From Valeriy Onuchin:
- new class TImageDump derived from TVirtualPS is introduced.
That allows to save canvas in GIF, JPEG etc, image formats in batch mode.
This patch is introduced to check the portability of the code on all
platforms. More additions coming soon to:
- text rotation
- correct text alignment (y-centered)
- 1pixel frame drawing
- fix saving in PNG format
- speed optimisation
