also enable more strict warnings for BLF (which had some incorrect casts).

takes a key as an arg and isnt popping any element from the hash as you might expect).
add BLI_pophead/tail, since getting the first element from a list and removing it is a common task.

render.
Printing text on the color grid image would initialize font glyphs from a thread at
the same time as the UI, causing conflicts. The freetype glyph renderer needs to be
mutex locked because it uses a shared buffer internally even when rendering for
different fonts. Also needed to change the image generate function to use the render
monospace font to avoid conflicts in blenfont.
What's still weak in the blenfont API is that there is no distinction between a font
and a thread using that font to render with some particular size, style, etc.

Added "Panel Title" style to Theme settings.
Allows to make these nice larger or draw differently.
Also tried to put hinting in Style, but this needs to be a per-font
setting. uiFont data is still not being saved (also not allowing
to set own font files for UI). That's a todo for 267 then.

applied to the characters y offset causing out of bounds pixels to be requested from glTexSubImage2D().
also clamp width, height of the character bitmap to the bitmap bounds since this can still happen for very small text (2-3 pixels high).

- Mipmaps are generated in BLF when drawing text in-game. In that case, padding around each glyph is increased to prevent bleeding.
- Texture filtering is turned on for in-game text.
- All glyphs are now "twisted": the leading edge is brought a small distance forward, to prevent z-fighting in overlapping (kerned) glyphs. This happens both in the game engine and the rest of the UI, but should have no effect in the UI due to Z-compression in the clipping matrix.
Reviewed and approved by bdiego; see patch [#29882] in the tracker. Tested by dfelinto.

As Campbell point, this is to avoid call glGet/glTexEnvi
on each character.

[#25834] no color of textobjects in game engine when combined with
textured objects
[#26893] Curruption of displayed text (debug properties/fps info or bgui)
when using animated/tile uv mode
The first bug was beacuse a bad mode on the texture environment, now
we save the current glTexEnvi, set the one that we need, draw and
restore the original at the end.
The second was because a missing call to glLoadIdentity for the
texture matrix and as we do before, now we do a gl-Push/Identity/Pop
for this matrix to.
The first problem was solved by Kanttori and the second by Dalai.

uninitialized memory found by valgrind.

glGetIntegerv(GL_TEXTURE_2D_BINDING_EXT, &cur_tex);
... with shadow enabled glGetFloatv(GL_CURRENT_COLOR, color) was called twice per character as well.
Now only call glGetFloatv(GL_CURRENT_COLOR, ...) once per string and only when drawing with shadow or blur, texture bind is stored in the font.
Gives 8% overall FPS speedup when displaying heavy UI in my test.

ASCII lookup table wasn't being freed when when the rest of the glyphs were.
Also found own bug where mesh stat text was using wrong sized array (char[3] as char[4]).

Remove the XXX code from blf_glyph.c and use the pointer
inside the FontBLF struct.
If still have problem, let me know.

User Preferences
Using "no AA font" crashed, caused by commit to make static variables.
However, how this was ever meant to work... using such globals has to be
treated carefully. Fixed for now with XXX warning for Diego :)
Thanks to reporter Susanne H. to point at the right code!

python functions.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.

(userpref->system), with a great help from brecht (its been way too long
for me).
However as brecht pointed out that the non-AA text is slightly lareger
then AA'ed Text :S, i did not do anything about this as this commit was
just the option not the text drawing.
this commit also makes it possible to do all kinds of UI textrender options

If still fails, check & update Freetype (OS one or Blender's lib/).

A couple of new functions:
BLF_width_and_height - Merge of BLF_width and BLF_height in one call to avoid freetype2 stuff.
BLF_buffer - Set the buffer, size and number of channel.
BLF_buffer_col - Set the text color (the alpha is not used right now).
BLF_draw_buffer - Draw the text in the current buffer.
Also tweak a little the boundbox and draw function to avoid access the freetype2 and use the cache info.
By default the font size is 12, the UI still need work to allow change the font and size.

As Joe point on a previous mail, glBitmap don't work nice
on all cards and also some of the things that we can do
with texture are hard (or need that blender check the font mode)
to implement.
