Move GPD runtime fields to runtime struct

Annotations: Set better default name for new annotation layers

Note: Many of the add layer operators still need tweaks,
but this is a good start for the main ones.

Annotations: Restore color selector per layer

This shows up in the layer list, making it possible to quickly change it
inline, and to see what color the strokes in the layer are using.

Cleanup: Fix comments

Cleanup: Reformat line

Cleanup and code reorganization

Fix problems with Blur FX

The FX passes needed BLEND state enabled to get the right result.

Also, the multisample texture does not need 32F and can back to the default 16F.

GP/Annotations: Provide usage hints about the "Poly" tool

Annotations: Don't respect the "on back" option

This is too complicated for an annotation tool

Remove "Continuous Drawing" flag/mode

* GP Object doesn't need this as it has a proper "Draw Mode"

* For Annotations, it just got in the way and was a confusing
modal+blocking nuissance that randomly activates when you just
want to draw a quick line
