mistake in own recent commit broke op[encollada with mingw

- use python convention for headings
- use implicit examples rather than .. code-block::

fix for building with msvc, ssize_t is more correct but in this case its not going to give issues.

bpy Gotcha's section on bones by Bassam Kurdali, with some edit.
added some examples & notes too.

replace octal 0177 with 127 to be more clear, no functional change.

- use %u rather tham %d for unsigned ints in string formatting funcs.
- replace (strlen(str) == 0) with str[0]==' '

- fix for BL_Shader::SetUniform() missing out the last part of the matrix.
- particle.c wasn't setting all components of the vector when reading cache and setting dummy velocity values.
- some functions incorrectly took a float[3] argument when the 4th value was set.
- remove a few redundant lines of code.

BGE: Post drawing callbacks are now done per viewport instead of per scene. This is handy for things like having a different HUD for each player in a splitscreen game. To figure out what viewport you're drawing too, check the scene's active_camera.

fix for bug with all rotation modes being treated as euler by the BGE, this bug is in trunk too but fixing here because this code will replace whats in trunk.

also make initializers less verbose for ipo transform assignment.

remove deprecated & unused sequencer transform vars

subtraction on unsigned values didnt work as intended for copying ID's.

bugfix for procedural textures used as bumpmap with osa not rendering right, also remove redundant assignment.

remove deprecated & unused mat3_to_vec_rot and mat4_to_vec_rot functions.

bge py api XK_GameObject.linVelocityMin was returning linVelocityMax.

eek F4TOCHAR4 was assigning alpha twice too!, tsk tsk.

F3TOCHAR4 macro was assigning the same value twice (setting the alpha, then overwriting with 255).

sub_v4_v4v4 was taking float[3] arguments.

Revert back to FFmpeg from lib/<platform>/ffmpeg

Camera tracking integration
===========================

- Stop tracking when marker is too close to the frame boundary.
- Added marker margin to tracking settings.
- Added option to use auto-adoptation each N frames.
- Highlight keyframed frames on cache line with brighter yellow.

Merging r39634 through r39716 from trunk into soc-2011-tomato
