X otherwise noLoop() in setup means no drawing happens at all
040920 evening
X defaults for PApplet and PGraphics are different
o PGraphics has none.. PApplet has fill/stroke
X actually not the case, only that wasn't calling decent superclass
X set PImage.format as RGB by default?
X this was problem with rendering an image from PGraphics on board

............................................................
0071 or later (but high priority)
_ before graphics engine change, attach jogl stuff?
_ massive graphics engine changes
_ explicitly state depth()/nodepth()
_ move to new graphics engine
_ test with rgb cube, shut off smoothing
_ make sure line artifacts are because of smoothing
_ implement 2x oversampling for anti-aliasing
_ need to resolve rotated text in SCREEN_SPACE
_ SCREEN_SPACE is weird for text
_ does the font or PApplet control the size? (the font, ala java)
_ without setting the font, the values come out weird rotated text
_ get rotated text into the screen space stuff
_ make PApplet2 that handles full screen 1.4 mode drawing
_ api for file-based renderers
_ need to work this out since it will affect other api changes
_ size(0, 0) and then ai.size(10000, 20000)
_ size 0 is code for internal to not show any window
_ saveFrame(PRenderer) or saveFrame("name", PRenderer)
_ saveFrame gets called at the beginning of loop()
_ or is just a message to save the next frame (problem for anim)
_ illustrator export / rendering mode
_ also postscript or pdf export?
_ update illustrator code to use core api
_ even if not actually working properly.. just in naming of things
_ 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.
_ figure out how to handle cached images, multiple images
_ MediaTracker blocking is prolly making jar download really slow
_ http://processing.org/discourse/yabb/YaBB.cgi?board=Proce55ing_software_bugs;action=display;num=1089914280;start=0
_ mkoser wish list
_ filled polygons working with smooth()
_ z-clipping
_ light(x, y, z, c1, c2, c3, TYPE)
_ also BLight with same constructor, and on() and off() fxn
_ image(myg, x, y) doesn't work but image(myg, x, y, w, h) does
_ (image kind prolly not set right and so image() gets pissy)
