- - python or java routines to compute distorted coordinates,

tjl:
- distorted multi-page PDF view with xu links
! - abstractUpdateManager: option to animate without
! rebound (looks very silly for switching between zooms
! in xupdf)
! - limit mousing area to the real area of the paper.
! - serialization
! of xu links (as part of space?).
- script the demo, determine in detail all features
required.
- - Buoy placement
- - implement in Java, test
- redesign mosaics to save memory and allow more internal
! formats
anybody:
- - performance enhancements:
- - different internalformats for TexRects
- primitive uis to edit enough structure of xanalogical text and
pdf spans, as well as connections so that we can build the
focus+context structure
- - Buoys + libpaper bg for PDF files, text stream
- - further work on irregular frames - talk to Tjl
- fix text quality on OpenGL: enabling __GL_FSAA_MODE=4 on
NV17 (GeForce4Go) improves "make glinfo" appearance
dramatically. This would happen by making the mipmaps

papertest.py and others.
tjl:
- distorted multi-page PDF view with xu links
! - placepapers always evenly
! - exponential scale, exponential magnification in fisheye
! --> far, far better interpolation
! - use real coordinates when moving to / from buoy,
! i.e. buoy coords
! - show right page of buoy
! - source coordinates for xu links
! - python or java routines to compute distorted coordinates,
! both forwards and backwards (forwards is more important)
!
! - text
! - buoy edges? more magnification?
! - mouse clicks on buoys to work
!
! - use libpaper for backgrounds !!! !!! !!!
! - for tomorrow, only one pass (speed!!!) in the ones
! really used for the papers.
!
! - limit mousing area to the real area of the paper.
!
! - entry / link making bindings
!
! - better distortion
!
! - multiple instances of same pdf / text visible? --> keys?
!
- script the demo, determine in detail all features
required.
- redesign mosaics to save memory and allow more internal
! formats + at the same time, mipmapping improvements

+ Go through test/ and convert tests to either .py or move to basalt/
+ Some basic tests for gfx/
- check OpenGL texture size at run time, adjust mosaic and bg
+
+ + code to see from PDF file the number of pages
+ + code to automatically start creating images on disk from
