Makefile: introduce DESTDIR variable for staged-installs.
Applied some changes for MuPDF 1.3
Added PySide demo
Added David's GKS HTML5 logical device driver
Fixed several 'array out of bound' accesses
Changed memory order for GKS transformation matrix in C binding
Added imshow function
Added new colormap (COLORMAP_BONE)
pygr: small fix on raising exception

Plot:setLog{X,Y}: Exception Message contains min, max only if window is defined
pygr: code format/style
qtgr: new style signal slots
qtgr: code format/style
pygr: errorBar1, errorBar2 properties

PlotCurve: added properties for errorBar1, errorBar2
qtgrdemo: added ErrorBar controlled by checkbox
pygr: new window calculation

PlotAxes: calculate window for visible curves
if no curve is visible calculate min, max for  all curves
pygr: new base class GRDrawAttributes, new package gr.pygr.helper

GRDrawAttributes: new base class for pygr classes with line and marker properties
gr.pygr.helper: refactor: renamed Helper to DomainChecker and moved this and
ColorIndexGenerator to new package
ErrorBar: now derived from base class GRDrawAttributes, use line and marker
attributes in drawGR method
PlotCurve: now derived from base class GRDrawAttributes, replaces
getters and setters for LineType, MarkerType, LineColor, MarkerColor
pygr: new base class GRDrawAttributes, new package gr.pygr.helper

Merge branch 'develop' of ifflinux.iff.kfa-juelich.de:gr into develop
pygr: Plot.setLog{X,Y} rescale option

automatic rescale window for logarithm plot
pygr: bug fix: PlotCurve calculate n

calculate n if linetype is None
n necessary to draw symbols
Fixed some problems when resizing the NSView
gr, pygr, qtgr, qtgrdemo: gr.axeslbl custom tick labeling

new custom tick mark drawing mechanism:
- gr_axeslbl: takes two function pointer arguments fpx (x-axis), fpy (y-axis).
callback function gets NDC coordinates and input string as parameter and
has to draw the tick marks. If NULL is given gr will draw the tickmark.
- text2dlbl: internal function with callback function mentioned above as parameter.
calls the callback function if given otherwise draws the tickmark

pygr: added offsetXLabel and offsetYLabel attributes
custom offsets for x/y axes labels and legend
pygr: bug fix: do not set linetype on drawing a legend item if no linetype is set for this curve
pygr: remove old variables for custom tickmarks
pygr: removed old methods for custom tickmarks (getXtickValues, getYtickValues, setXtickLabels, setYtickLables)
pygr: PlotAxes: new methods for custom tick marks drawing: setXtickCallback, setXtickCallback
qtgr, qtgr.events: removed TickEvent and dependencies.
there is no need to inform the user about new tick marks because the callback functions are called directly by gr
