o check ordering of split() in java vs perl for regexp
X don't include empty chars in font builder
X .vlw font files are enormous with full charset
X check to see if the character exists before adding it to the font
X fixed (unreported) problem with char lookup code
o split() with multiple args (i think this is completed)
X http://processing.org/discourse/yabb/YaBB.cgi?board=Syntax;action=display;num=1078985667
X trim() not chop().. whups
X random(5, 5) -> return 5, random(6, 4) return error
X http://processing.org/discourse/yabb/YaBB.cgi?board=Proce55ing_software_bugs;action=display;num=1083275855;start=0

thesis / acg
_ make bagel more usable as standalone
_ breakout BGraphics (have its own BImage)
_ breakout BApplet into BComponent ? (fix out-of-bounds mouse)
_ possible use of BUtils ?
_ write documentation on general use
_ along with how to download from sourceforge (anonpass is blank)
_ needs to be used as a component, without applet
_ but retain functionality, ie. image i/o
_ exports pixels or a BImage or does MemoryImageSource itself
_ move math functions into utility library associated
_ with bagel, because those will be useful on other bagel platforms
_ pApplet will call BagelMath.whatever, so still looks like cos()
_ #ifdef to remove client and server code as well
_ break out BSerial as separate object like BVideo
_ include rxtx and the rest of that setup in subfolder
_ BSerial.flush and BSerial.available in object
_ need to resolve issues between rendering screen/file
_ illustrator-based rendering needs to work for ars projects
_ screen may be 400x400 pixels, but file be 36x36"
_ opengl export / rendering mode
_ currently implemented, but somewhat broken
_ finish this once all the line code is done
_ make possible to use buzz.pl to create versions w/ stuff removed
_ build gl4java for java 1.4
_ read table/csv formatted data into a matrix
_ pseudo-database format version of this that stores indexes to file
_ rather than loading the whole thing at once
_ more advanced splitting of files into rows/cols uses another class
_ other class also has concept for random access of lines
_ by storing the line positions, can access without loading all
_ into memory because some files will be too large
_ illustrator export / rendering mode
_ also postscript or pdf export?
_ version of Illustrator.java that uses bagel api
_ sorting of polygons/lines on simple painters algorithm
_ better lighting model to show darkness at various depths
_ maybe just ultra-high res bitmaps from gl
_ version of BApplet that replaces g. with ai. or pdf.
_ history.. add my diffs sketch
_ could just include a compiled version of the diff app, ala jikes
NEW GRAPHICS
_ stroke not set on flat_rect
_ when drawing fonts w/ sami's code, left edge has problem
_ 8-bit (alpha) textures not blending
_ near-plane clipping currently disabled for triangles, enabled for lines
_ (but culling offscreen triangles works.. but may have been
_ commented out by carlos)
_ sphere code needs only front face polygon
_ all triangles must be counter-clockwise (front-facing)
_ some way to properly quit sketch when stopped
_ if people have other threads they've spawned, impossible to stop
_ http://processing.org/discourse/yabb/YaBB.cgi?board=Syntax;action=display;num=1067383998
_ rewrite bagel code..
_ for this release, because it will break things along with the lib stuff
_ switch to PImage, PApplet, etc
_ update() mode needs to be hacked in
_ separating of BGraphics and BApplet
_ change copyrights on the files again (to match ?)
_ proper lineweight
_ camera clipping
_ put screenshots into their sketch folder
_ http://processing.org/discourse/yabb/YaBB.cgi?board=Syntax;action=display;num=1046185738;start=0
_ add a method BApplet.setPath() or something like that
_ add color(gray) and color(gray, alpha)
_ http://processing.org/discourse/yabb/YaBB.cgi?board=Proce55ing_Software;action=display;num=1074180764
_ light(x, y, z, c1, c2, c3, TYPE)
_ also BLight with same constructor, and on() and off() fxn
_ update illustrator code to use bagel api
_ even if not actually working properly.. just in naming of things
_ new networking client from simong
_ simong lighting code
_ screenGrab() at the end of a draw mode program is problematic
_ app might exit before the file has finished writing to disk
_ need to block other activity inside screenGrab until finished
_ catch security exceptions around applet i/o calls
_ not just for saving files, but provide better error msgs when
_ attempting to download from another server

GRAPHICS LIBRARY
A hybrid of OpenGL (3D Graphics) and some aspects of Postscript (Fill, Stroke)
The graphics library is called Bagel, which is an internal name.
BAGEL / Rendering
b _ picking
b _ what is the API for picking?
b _ ability to write data other than image into the buffer
b _ user can introduce new kinds of buffers at will (!)
b _ lists of names of objects, or the 'line number' buffer
b _ but how to determine *where* on object the hit occurs
_ add option to sort triangles back to front so alpha works

b _ lines
b X rewrite line and stroke code, it's a buggy mess
b X lines become 2 pixels thick after a 3D transform
b X better handling of single-pixel special se
b _ flat_line_retribution is a hack, can go away
b ? make sure line() commands don't try to have a fill
b _ box is not opaque
b X problem is that lines are drawn second
b X one pixel lines have no z value.. argh
b X bug re: 3d depth sorting on lines

b _ strokeWeight is still broken
b _ setting stroke width on circle makes odd patterns

b _ i.e. glyphrot with scale set to 4
b _ or at least that things get ridiculously slow
b _ clipping issues here.. but also something in scan converter
b X not clipping areas from offscreen
b _ huge geometry slows things way down
BAGEL / Details
1 _ toxi ellipses don't adapt properly with transformations
1 _ what is the stroked version of a sphere? a circle?
1 _ non-homogenous coloring for curve vertices
1 _ properly interpolate
1 _ too many push() will silently stop the applet inside a loop
1 _ test winding polygons in different directions
1 _ test lighting to see how it compares with gl
1 _ better lockout inside beginShape() to keep other things from happening
1 _ is quad strip broken or not behaving as expected?
1 _ may be correct, it worked for nik
1 _ inside draw() mode, delay() does nothing
1 _ delay might be a good way to signal drawing to the screen/updating
BAGEL / Fonts
1 _ sbit font support
1 _ both reading and building sbit fonts
* _ mac -> vlw (or sbit?) font converter
* _ need to also read the fond for metrics
