This commit adds an experimental effect strip to the sequencer: "Title
Card".
This is useful for adding simple one-line text section headers or
"title cards" (i.e. title + author/contact details) to video clips,
which is often seen in demo videos accompanying papers and/or
animation tests.
See http://aligorith.blogspot.com/2011/06/gsoc11-simple-title-
cards.html for some more details on usage.
Code notes:
- There are a few things I've done here which will probably need
cleaning up. For instance, the hacks to get threadsafe fonts for
rendering, and also the way I've tried to piggyback the backdrop
drawing on top of the Solid Colour strips (this method was used to
keep changes here minimal, but is quite fragile if things change).
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
This patch adds adjustment layer tracks to the sequencer and does some cleaning
up of the code.
What's an adjustment layer?
Think of it as an effect track, which takes no explicit input, but alters
the output of everything down the layer stack.
So: you can add several stages of color correction with it.
And: you can even use it with metastrips to group several adjustments together.
mouse coords would with cont. grab would wrap at short.
use mouse coords as int rather then short.
this problem still happens on linux because of XTranslateCoordinates
Using search for operators showed ambigious names like "Duplicate" or "Delete".
Default names should give at least a descriptive label. In case operators
are collected in a group name-shortening should be handled separaly.
was not recursively restoring sound strips on paste.
also found many duplicate functions were defining the transform mode as in int but getting as an enum, use enum for both now.
* Copying/pasting sequence strips didn't properly check for unique names between the copied/pasted strips, so the rna paths of copypasted strips couldn't always be checked properly.
The sequencer made it's own copy of the Markers keymap, which was
inconsistent with the rest of Blender, making things confusing to use.
I've removed these duplicate keymap entries, and also changed the
conflicting hotkeys for Metastrips.
Metastrips now use the same hotkeys that their NLA cousins use:
Shift-G to add, Alt-G to remove; These were chosen since in user-
terms, metastrips are more like "strip groups"
also minor functional changes
- OBJECT_OT_make_links_data() type property is now assigned to the operator property (so popup menu can find it)
- removing BG image now returns cancelled if no image is removed.
animation editors (DopeSheet, Graph Editor, NLA, Sequencer) ==
=== Usage Notes ===
In animation editors, marker operators will only be considered while
the mouse is hovering near/over the horizontal scrollbar (i.e. where
the markers usually appear). That means, in order to do something to
the markers, just position your cursor in line with the row of
markers, and then use the same hotkeys you'd use in the TimeLine (so,
unlike in 2.4x, no more need to hold down extra modifier keys for this
case). In the TimeLine, nothing changes, so you don't need to worry
about mouse placement there :)
=== Technical Details ===
Since early 2.5 versions, this functionality has been disabled, as the
markers were always getting evaluated first, and hence "swallowing"
all the events before the editor's own keymaps could access them.
In order to get this working again, I've had to give every marker
operator a "wrapper" invoke callback which performs some checking to
ensure that the mouse is close to the markers (vertically) before the
operator will try to be run. This wrapper also makes sure that once
the operator has finished running, that if it didn't manage to do
anything, then the editor's own keymaps get to have a go.
The vertical tolerance used is currently 30 pixels (as was used for
the borderselect operator).
=== Other Assorted Changes ===
* Gave marker operators dependent on having selected markers to
operate on suitable poll() callbacks. These new poll callbacks ensure
that there are selected markers for the operator to operate on,
further cutting down the number of places where markers may override
standard hotkeys (and avoiding calls to the wrappers too)
* Simplified some of the selection code
* Made some formatting tweaks for consistency, and in one case so that
my text editor's function-list display doesn't get confused
"Numpad 1" shortcut to set preview view zoom to 1:1 (i.e. 100%) did
not exist in View menu. While investigating this, I found that the
operator was missing a description/tooltip, so added one too.
