box to 0.5 pixels instead of 1.
* (ComputeCoordinates): Fixed the way ALIGNED was computed
it didn't work with skew, and had other bugs.
* (GetClipVertices): Fixed a bug on the tristrip returned
when the rectangle is not aligned on axes. The order of
the returned triangle vertices didn't describe a rectangle.

items or named transforms.
* Added a tset method to set a transform from given matrix
values.
* Reformat of the code to suppress braces inconsistencies
due to ifdefs.
* Added a skew method to skew a transform both along x and y
axes.
* The transform command now accept the special tag device as
source and destination. It accept also a named transform
as source and destination.
* Added a reserved tag identity as possible source transform
for command tsave.
* tsave can now take a named transform as source.

being an unsigned causing a mis-coloring of the history
when -lastasfirst is on.

INV_TRANSFO registered with an item prevented the registration
of other more specific reasons. The text item exhibited the
symptom when interleaving a text modification between two
changes of its transform. In this case INV_TRANSFO prevented
the registering of INV_LAYOUT.

control point list was not correctly updated.

segments instead of straight line segments.
* Added a configuration option -followpointer to try
some optimizations of motion event processing under
application control. The motion events are still
emitted but the enter leave processing is suspended
when this option is set to zero.

behaviour led to a core dump (pb with reference
couting).

Added code to construct the valid region of
an image (shaped) even if TkPhotoGetValidRegion
is not available (perl or not a photo).
Added a fun telling if a point is on the active
area of the image.
Changed the internal api for using images to
match the changes above.
A tkfont reference is kept for each txf using
the font so that the font can be freed if no
longer used.
Use of the max texture size is now reliable and
texture allocation for fonts start with the largest
tex and increase the tex height from 64 to the max
tex limit. This seems to work ok for large fonts.

the -symbol attribute for tracks.
Updated the option code to follow the new image behavior.
The scrollbar protocol in perl has been slightly debugged
but still won't work, more on this later.
Update the font code to load fonts infos (GL) only when
receiving the realize event.

Corrected a bug in rectangle tiling (textures) under openGL
when optimizing for aligned rectangles.

it is taken for the gradient starting angle, the center being 0,0.
If two values are given, they are taken as the gradient center, the
starting angle being 0. If three values are given they are the gradient
center followed by the gradient starting angle. If four values are
given, they are two points defining the center and the angle/extent
of the gradient (vector based definition).

The font texture is loaded when doing the first drawing.
Changed the api of ZnConfigureAttributes.

Changed the ZnConfigureAttributes api.
The texture font allocation is postponed
until need for drawing. At that time the
GL engine is guaranteed in the right state.

if their images changed.
Changed the ZnConfigureAttributes api.
The current position symbol is now correctly read
from the -tracksymbol option and not statically
fixed.

of attributes from fields even if the item record is needed.

api for reading videomaps. This enable using zinc and data right from
starkits.

update mecanism is now fully fonctional.
Picking of shaped icons is know correct in all cases including
rotated icons in both X and GL environments.

Adaptation for the new gradient structure.
Added the processing of conical gradients.
Simplified gradient preparation only one function
need to be called ZnComputeGradient.

by a center and an angle or a vector.
* Added alternative vector based gradient syntax. This is
effective in axial and radial gradient types.
* (ZnGetGradient): angle, position, control can be
real numbers
|
|
* (ZincObjCmd): Fixed a core dump when destroying zinc after
an error occured during the first Configure. The tesselator
got inited a bit late.

Use of the new ZnGetGradientPixel function in X.
Added an optimized case for tile filed rectangles
when they are aligned with the pixel matrix (openGL).
This can dramatically boost performances on some applications.
|

|
|
* Use of the new ZnGetGradientPixel function in X
* (Pick): Changed the picking method used for curve interiors.
The new one is based on triangle strips/fans not on the outlines.
|
|
Use of the new ZnGetGradientPixel instead of ZnGetGradientColor in X.
