Fix for 2.66a
Some editors in Blender (Like Graph) have "maxzoom" set to 0, which caused the
MMB zoom sensitivity to be minimal. That used to be much more responsive, restored
it to how it worked before.
|
|
|
|
CTRL + MMB zoom in 2d editors now depends on 'max zoom' level. This makes
zooms in UI (very limited) go smoother, but for fcurve or timeline it's same.
|
|
Ancient annoying thing for zooming in 2d views: when a view was restricted to keep
aspect ratio, it only allowed vertical or horizontal MMB-drag zooms, depending
portrait or landscape size of editors. Same for trackpad and magic mouse.
Now vertical zoom drag always works for editors like buttons, nodes.
|
|
Trackpad zoom (swipe + CTRL) direction was inverted compared to MMB-drag
or scrollwheel usage. In the 3D viewport it was OK, in all others not.
Now the same physical gesture maps identical to zooming everywhere. Or to
recap (with blender factory settings)
Zooming in:
- MMB-drag, move mouse towards screen
- Scroll wheel, move finger towards screen
- Magic Mouse, move finger towards screen
- Trackpad 2-finger swipe: move fingers toward screen.
To make this extra confusing: this is only consistent if you set your system
to inperpret trackpad swipes as "inverted" (pan view left = swipe to right).
This is a typical default, although Apple wants you to call this "Unnatural" :)
Next commit will be testing on laptop if all pinch gestures zoom consistent.
And following to that, a sensible user preference to map trackpad use for
Blender yourself, to invert system defaults again. :)
Blame and thanks goes to Sebastian Koenig, for his perseverance on getting this
solved :)

- UV Image editor and other 2d views didn't zoom for CTRL+swipe yet.
(2 finger trackpad, 1 finger mighty mouse)
- Switched defaults for 3D window swiping...
- default rotate view
- SHIFT for translate
- CTRL for zooms
This makes all editors use 'swipe' like 'middle mouse', and not
like scrollwheel (as in releases).
This is nice for consistancy, but it still feels a bit weird...
Of course users can config this in keymaps. We need a sensible
default though, and to make a 2D input input device behave like
middle mouse seeems more sensible than like a 1D wheel...
Proposal therefore for defaults:
- 1D scrollwheels: zoom in 3d, zoom in 2d, but scroll for list views.
- 2D trackpads: pan for all 2d views, rotate for 3D
I'll check with frequent trackpad users about this and we can freeze it
before release. Give it a try :)

Now scrollbars correctly hide and show, making space for the actual contents
in a region. It solves several old hacks, and puts view2d code a bit more
back in control as well.
Implementation notes:
- The view2d mask feature is working again
- The #define V2D_SCROLL_HORIZONTAL_HIDE means: "turn on hiding".
- Code for UI_view2d_region_reinit() is enforcing better standard view settings
But... two hack/patches needed to be added:
- Region panel drawing: if after generating the button panels it appears
a scroller hides or reveils, it calls all the generating code again.
(a simple scale doesn't work due to rounding differences in layout code)
- View2d code that maps 'tot' and 'cur' rects: if this code detects that
the mask changes, it calcs the map code again.
Also a bugfix (issue in 2.65)
- The left/bottom area split widget was drawing 1 pixel too large sometimes,
leaving bad trails on moving area dividers.

- use DummyRNA_NULL_items to replace empty enums.
- replace calloc with malloc in copy_dverts since its copied over after.
- add wmGesture->userdata, so operators that use gestures have somewhere to store their own data (not used yet).
|
|
User preference "Zoom Scale" didn't work correct for 2d views.
(was calculating center of region badly).
|
|
- minf, maxf, mini, maxi --> min_ff, max_ff, min_ii, max_ii

Was discussed in De Balie with lots of artists and we agreed it makes more
sense to behave this way
|
|
places as well, but it's quite large change to be done before 'a' release.
For now ignore zoom inverse for 2d view to keep things consistent,
would be re-implemented for all areas after this.

refactoring

Initially issue was caused by opposite MMB-Drag zoom direction in nodes editor.
Made it so MMB-Drag in negative axis direction (down for Y axis and left for
X axis) would zoom in, moving in opposite direction will zoom out.
This could kind of break muscule memory, but after discussion with Campbell
decided it's not so big a problem -- seems users weren't related on direction
of zoom in and just waved mouse around until zoom is correct. And now muscule
memory should even be a bit better -- drag zoom is unified between different
areas.

it always recalculated.
|
|
|
|
also remove some redundant conversions int -> short -> int
|
|
It was a regression since disabling Y-axis zooming in sequencer.
Now check region type and allow all kind of zooming for preview
region.

also the compositor bounds (used for scroll bars), were only calculated when pressing the home key in 2.63, how this is updated on draw

border zoom, view selected, view all.

- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
|
|
- make sure defaults are not assumed (so reuse last settings doesnt
override)
- replace 0/1 for TRUE/FALSE defines.

Disabling mode switching in panning in 2d as it is disabled in 3d also.
Apparently, it is a not good idea to call modal method from a modal method as the last won't be canceled.
