=== Text tools proposal ===

* Possibility to perform boolean operations on the text objects itself. Those operations should be possible by using curves, not meshes (maybe too)

From a users perspective it's not understandable why you should convert your text into a mesh to process it further. Apart from that, you can't edit the text afterwards. So this is really not comfortable and causes massive production time loss!

== Ideas ==
* Texts should be treated internally like curves
* No conversion should be needed to make text objects adjust its form
* There should be control points on the text object that can be altered like on ordinary curves (like you would have converted a text to a curve and you would drag the control points around).
* They should be animatable through hooks, shape keys and lattices

= notes from gexwing =
The current Text system is not realy advanced, Text objects can not easily be animated, which is an important factor in Motion Graphics/commercial type work. We hereby propose some changes, which would make the workflow more non-destructive, more advanced in terms of animatability, and should leave us with cleaner output meshes.

== Proposed improvements ==
* We propose a Type of object, which has the properties of 2d closed curves and text.
* Text should be treated as curves (same as the current output after converting it to a curve) all the way through the pipeline, whitout losing the ability to change the text.
* The Object Type should be able to handle 2d boolean operations besides non-even filling, which is the only thing Curves can do now. (like Add/Subtract of new Masking Layers)
* Handling those modes could benefit if there was a Curve/Lext Layer-List, with modes for each layer, hiding layers could also be usefull for keeping backups of a Text-Layer if one realy needs to convert it to a Curve-Layer for further changes.
* current features of Curve Geometry which could easily be adapted for this compound type: Offset, Extrude, Bevel Depth and Resolution
* Beveling of the object after extruding should be handled by bevel code (GSoC Project?). It should not generate overlapping bevels like current implementation, rather clip it.

== Generated Geometry ==
* Curve intersection points should be calculated and placed exactly, to fix current flickering or sometimes failing non-even fillings of curves.
* The Geometry generated by this Type should be consisting of n-gons, taking full advantage of the new bmesh sytem.

== Animation ==
Text and 2d Curves should allow for more non-destructive animations. This could be accomplished by having a range of simple "2d modifiers", with options on how they influence individual characters on text-objects, frame-offsets for characters, influence on object offsets, also randomizable.

Some Ideas for 2d modifiers:
* Translation, Rotation, Scaling
* Specific Text effects like "typing in", "fly in"
* Simple Deformations (like the Simpledeform Modifier)
* Warping (Lattice?)

== Problems to overcome ==
* n-gons: with bmesh, other parts of blender should be converted to take full advantage of it's features. b-mesh not yet allows for inner edges (i.e. holes), which would be helpfull for text and 2d booleans. This means one additional face per hole.
* Tesselation: the current Tesselator generates wrong geometry for some non-convex n-gons, the solution to this problem should best be adressed in the tesselator itself. As workaround, all non-convex n-gons could be split into convex ones.

== Pro's / Cons' ==
+ easy non-destructive text animations

+ Customizable by fast 2d booleans/adds

- order of execution of layers is important (current 2d curve non-even filling is not)

- not every effect may be easily achievable, this would probably require a full node-based approach, which is more than this proposal aims for.
