- enhanced methods for storing/retrieving QgsDataDefined in a
string map
- add method to QgsDataDefinedButton to update parameters for a
QgsDataDefined
- deprecate an unused method
- const correctness
This change allows for some cleanups to the built in expression
functions, by making it possible to differentiate variables
(eg $feature) from functions which don't require parameters
(eg uuid(), now()... ). Also adds aliases for uuid(), now(), and
pi().
This reverts commit b4a85471978b59b129c0299dfd14c1af00fef743.
The template based approach was not cross-platform friendly. When
cross-compiling for Android it caused a new instance of every singleton per
shared library.
Mostly using the magic statics pattern instead now:

Important things to remember for crash on exit:
* QgsNetworkAccessManager needs to die before QApplication
* QgsMapLayerRegistry needs to be emptied before QgsProviderRegistry goes away
And finally:
DON'T USE SINGLETONS!
They are for "one and only one" and not for "happens to be only one" situations.
* fix build on windows
* fix grass build on precise (using cmake <2.8.8, ie. without INCLUDE_DIRECTORIES target property)
* support desktop & browser shortcut for GRASS 6/7 in OSGeo4W nightly build
The graduated symbol renderer now allows to use varying size instead of
varying color.
The classification remains the same an tabbed size/color in the gui
allows the use to choose one type or the other.
This option (located under the symbol advanced menu) disables the
automatic clipping of lines/polygons to the canvas extent. In
some cases this clipping results in unfavourable symbology (eg
centroid fills where the centroid must always be the actual
feature's centroid). (fix#9757)
This commit adds a new framework for implementing paint effects, which
modify the results of QPainter operations to apply visual effects
such as drop shadows and blurs.
The initial implementation allows for effects to be applied to entire
layers and individual symbol layers.
Included are a drop shadow, inner shadow, blur, inner glow, outer glow,
colorise and transform effect. A "stack" effect is also implemented
which allows other paint effects to be combined in various ways.
