* Fix for crash using texture nodes in displace modifier

Modifier code was asking for filtered textures without sending derivatives.
Disabled this and also checks for filtered/non-filtered.

Brecht, I assumed this was ok due to the existence of the p->osatex variable
- if this isn't what you had in mind, please change or let me know :)

improve brush size keys so they dont change by 20 each time (bad for small brushes), added wm.context_scale_int() operator.

option to use offscreen opengl drawing with the sequencer scene strips.

warning, uses bad level call, will need to resolve very very soon!

Revert inadvertent ffmpeg changes.

scons build systems

Allows static libs to be passed correctly to the linker (i.e., full paths to
libs which end in ".a" are passed to linker without processing). I've been
using this on linux release builds since sometime around 2.49 without problem
but hesitated to commit since I don't know if it would affect any other
platforms. If you're using static libs on another platform and it breaks,
let me know.

image re-project now uses offscreen render function and has input for render size.

unrelated changes that ended up being more trouble to commit separate...

- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile

- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.

MSVC projectfiles_vc9:
* maintenance

move render operators into their own files, render_internal.c & render_opengl.c, rather then have them in the screen module.
also rename render operators SCREEN_OT_ --> RENDER_OT_

Bugfix: multires save external was not working. Just disabled operator poll
for now, but there's actually a deeper issue here, the modifier is no longer
in context after the file browser, not sure how to solve this.

Depsgraph: more tweaks to last commit to get it actually working
int more complex files.

Depsgraph: always execute scene camera as if it was on a visible layer,
because even if it is not it can still affect the 3d view or render.

Send object's modifiers were changed in conversion operator.
This will prevent displaying data on modifiers page after conversion is over.

Change airbrush rate min/max to allow lower values and add separate
soft/hard limits for even lower/higher ones.

- Fixed trouble with rendering curves with disabled modifiers, which are
disabled for realtime displaying but enabled for rendering.
- Calculate tex space for curves before modifiers applying.

Fixed segmentation fault when converting mesh to mesh with non-empty modifiers stack.

Fix [#21469] long paths can't be scrolled with the mouse

workaround for [#21486] Python debuger pdb don't work

setting sys.stdin to None is done so python wont lock blender when it tries to read from the input. - help() from the console does this.
Running blender with -d keeps the stdin so python debugging can work. add info in the help message about this.

eventually it might be best to replace sys.stdin with our own object which interacts with the console but this is not trivial.

commit from r27250 to fix bug #21433, broke local axis rotation for pose bones and objects.
commented fix and reopened report.

Ctrl+RMB support for selecting markers when sync markers is enabled.

Fixed segmentation fault error when entering curve's edit mode when
there is sufsurf modifier first in the stack.

Some optimizations in curve_calc_modifiers_post():
- Calculate allverts array only for curve modifier applying to curve
without derived mesh.
- Do not calculate deformedVerts array each time deformation modifier
is applying to derived mesh.
