Blender Git Loki

* Adds touch type to GHOST
* Adds touch event structure to GHOST (not fully implemented)
* Adds generalization of Windows system touch for MinGW and beginnings of support for MinGW-w64 and MSVC

UV transform correction tool
=============================
* Fix transformations to choose correct face, also comment some annoying
debug code. With this commit the tool should work very well for interior
vertices. Coming next: seam support. Final tweak will be done to support
exterior vertex moving.

Enable Ctrl-F for rake brushes

Merge from trunk r47354-r47744

UV transform correction tool
=============================
* fix the projection in uv space and some fixes for selecting the face
to project on. The code still does the wrong choise sometimes.

This was preventing panels in the 3D view from animating open and closed.

Texture Rake brushes
====================
* Random angle for brushes

Texture rake brushes
====================
* User angle option now usable.

Bake Object Animation export Fix.

Texture rake brushes for texture paint mode
===========================================
* Reading into the code, i am starting to get the hang of what is going
on :)
* I disabled the texture rake for projection paint because it didn't
work too well (will check why next). I suspect a sampling offset issue.
So I started implementing rake brushes for regular non-projective
texturing and uv/image viewwer. This commit makes this work :). I will
probably have to move the rotation part from the BKE_brush_sample_tex
function and modify the coordinates directly. This will ensure that for
projective or even fixed mode texturing this will work as expected (?)

merge the paint fix

merge with trunk 47606

warning fixes

GPU_immediate.h: casting a pointer directly to a GLboolean and a complaint about how I wrote GPU_SAFE_RETURN
text_draw.c: uninitialized and unused variables. also some style changes

missing argument to BLF_draw_lock

I performed a proper management when selecting some vertices, we must detect the border with the flag BM_ELEM_SELECT in the faces around vert.

missed files

For some reason BLF_draw_font is very sensitive to every little change I make.

Default alpha for GLubyte is 255, not 1 (!)

fixed some macro wierdness (always use parenthesis). The other changes are just formatting
