[Bf-committers] Quick proposal for "Print Size" settings mode

[Ton Roosendaal]

Hi,

I think this is highly disputable to add this by default in a 3D  
gfx/animation suite. It can even be easily achieved with a Python  
plugin, offering the GUI in a Script Window. Such specialist additions  
is exactly what we have a scripting language for.

My main concern however is that the general audience, especially most  
DTP artists, haven't the slightest clue what a DPI actually means, and  
how to create properly 3D graphics for printing. Blender output is  
*not* comparable to output of normal 2d layout tools, but instead  
compares to the output you get from a (digital) camera.

Since rendering is done only with pixels in 3d software, with for each  
pixel an enormous overhead in CPU in memory, I really recommend to keep  
PIXELS as presented standard in Blender. I'm really not looking forward  
to a bug report stating "Blender crashes on rendering a 30x20 inch  
image with 600 DPI".
