Restored the UI for access to the GP layers.
There are still a few minor bugs here:
* Wrong icons on the toggles - even when they're enabled, they only show a single state
* The ID-template doesn't seem to be showing up. Dunno what's going wrong there...
* When starting Grease Pencil from the toolbar, strokes are now started only when a click-drag begins.
* Made the 'straight-lines' option an RNA property for the operator
* Added an exec() callback and relevant stroke-collection stuff so that interactive redo/changing settings can work.
WARNING: this is highly unstable here - keeps crashing though I cannot determine the cause yet.
renamed RNA properties.
x_offset, y_offset -> offset_x, offset_y, this order is more common in rna.
render.border -> render.use_border
render.placeholders -> render.use_placeholder
render.no_overwrite -> render.use_overwrite
Again, please try not to break scripts - at least grep the release dir for the names you change.
- rna material property rename
gloss_amount -> gloss_factor, since its from 0.0 to 1.0, prefix factor is used on other material settings.
reflectivity -> reflect_factor
* Shuffled some code around, and renamed some functions used for getting context info
- Split UI-buttons into a separate file from stroke-drawing code
- Removed some obsolete code (i.e. old paint code that used to be in _edit, but which has been moved to _paint).
* Made drawing in 3D-View default to using the active object as the owner of the Grease Pencil data. For now, the drawing code will therefore only show the GP data for the active object only. More work to come on this.
* Fixed freeing code for Objects/Scenes with GP data.
Also ported some name changes from the materials UI script to RNA to keep these consistent. Animation editors always show the RNA name after all, so it's good to keep the names similar.
* Wrapped Grease Pencil datatypes in RNA.
* Hooked up Grease Pencil access in RNA (i.e. via Main, ID, and Scene)
TODO:
Updates to properties are currently lacking property-update calls, since there's no good notifier for this.
* Changed the hotkey to simply be:
Hold DKEY, click+drag using Left-Mouse (draw) or Right-Mouse (erase). How to get tablet erasers to work (via keymaps) is on todo...
You can simply hold DKEY until you've finished drawing, thanks to the nice way that keymaps can support standard-key modifiers now.
* Eraser works now too.
* Realtime updates now work again
* Fixed problems with clicks to start drawing resulting in a stroke being ended.
* Changed the hotkeys to Ctrl-Alt-Shift-LMB (draw) and Ctrl-Alt-Shift-RMB (erase). Still very temporary stuff, will probably change these a few more times as I experiment with new approaches.
This commit is the start of the new Grease Pencil implementation. I've just ported the old code to make it work with operators, and to store its data in Grease-Pencil datablocks.
However, this is currently still really buggy, with only the barebones of the drawing/creation tools restored (no UI panels, no options). To use (not recommended), use D+S+move_mouse (and click when finished) for now. There are some rather serious event handling errors going on here...
* Fix for plane material preview render. Now, light cache aborts if there isn't enough volume, and falls back on non-cached single scattering. It still doesn't make much sense to render a plane as a volume, but for now in the preview it will shade the region in between the plane and the checker background.
Also, made the Outliner's horizontal scrollbar work better for keymaps view. It's still using an approximation of the width, but at least you can scroll now.
