- The basic layer for Themes in place!
- currently only implemented for 3d window
- create as many themes you like, and name them
- default theme is not editable, and always will be defined at startup
(initTheme)
- saves in .B.blend
- themes for spaces can become local too, so you can set individual
3d windows at theme 'Maya' or so. (to be implemented)
- it uses alpha as well...!

API:
This doesnt use the old method with BFCOLORID blahblah. The API is copied
from OpenGL conventions (naming) as much as possible:

- void BIF_ThemeColor(ScrArea *sa, int colorid)
sets a color... id's are in BIF_resources.h (TH_GRID, TH_WIRE, etc)

- void BIF_ThemeColorShade(ScrArea *sa, int colorid, int offset)
sets a color with offset, no more weird COLORSHADE_LGREY stuff

- void BIF_GetThemeColor3fv(ScrArea *sa, int colorid, float *col)
like opengl, this gives you in *col the three rgb values

- void BIF_GetThemeColor4ubv(ScrArea *sa, int colorid, char *col)
or the one to get 4 bytes

ThemeColor calls for globals (UI etc) can also call NULL for *sa... this
is to be implemented still.

Next step: cleaning up interface.c for all weird colorcalls.

- accidentally removed 2 lines in this file that made previewrender not
showing up...

- fixed edge selecting... :)

- bone selection armatures fixed!

- fix for drawing buttons in fileselectors, it used an old exception
and special 'EMBOSSF' drawing function. Now complies to standard.

- fixed correct drawing of frontbuffer vertices... it still gives some
nice increased interactivity when selecting in slow drawing situations.
nevertheless, can be worked on later once, to make it less hackish. :)

- fixed editing vertices again!

I had to clean up very old calls to switch matrices for 3d windows.
To make it more clear, I've introduced defines for the infamous persp()
function:

persp(PERSP_WIN); sets matrices at pixel level window
persp(PERSP_VIEW); restores matrices back to 3d drawing
persp(PERSP_STORE); only called once, to store correct matrices

I will now check on frontbuffer drawing of vertices... it's very doubtful
if it's used still correctly, was only meant for visual speed in the
early nineties you know. :)

- further work on view3d panels:
- you can close them (x icon) or press ESC
- option to open panel at mouse location (try Nkey)
- using 'collapse' (triangle icon) stows header in bottom
- opening again restores at old location
- dragging panels or zooming clips nicely with window

evaluate: an 'auto close' when mouse goes outside panel

Warning: vertex selecting still broken! :) It's 2 am now, bedtime...

added interface_panel.c to msvc 6 projectfile

- removed all #include "interface.h" from files. this is a local/internal
include only (use BIF_interface.h instead)
- split up interface.c in two files: NEW: interface_panel.c
- removed the temporal text files

WARN: FIX AUTOMAKE AND MSVC!

- fixed drawing errors in constraint panel
- join 3d window could crash... unchecked pointer in interface.c
- setting align in buttonswin caused stripes to draw in view3d-panels
- fixed events for new 'background and view settings menu'

- Added ICON_MENU_PANEL

- Added icon to indicate floating panels in menus: ICON_MENU_PANEL
- Added it plus tiny edits to view3d menus

- More code for handling Panels in other windows.
Added the 'Nkey' object menu as Panel now. Live updates, whoohoo!

closing them, minimizing, etc will follow. first bring back vertex
selection :)

- Various cosmetic fixes to menu buts in headers, alignment etc.
- Make text fields' text black when deselected, white when selected (editing)

- Modified drawing of ICONROW controls to be clearer,
more consistent and logical. (ICONROWs haven't
scrolled left/right in years!

More detailed tweaking of headerbuttons positions can come when
more menus are finished

- added text labels to the drawtype menu in 3d view header

- fixed warnings in drawmesh.c
- with mouse in Panel, padplus/minus defines scaling of Panel... dunno if
this is the correct key. thats for later to worry!

Forgot to mention in previous commit:

- Panels now have a uiSetPanelStyle() API call. Is under construction...
now for test purposes mostly.

- expanded internal windowmanager that it allows button panels in any
window (type)
- each SpaceData struct (not the window!) can get 'block handlers'
assigned, basically event codes that invoke drawing button panels.
- this is saved in files, and Panels behave in any window like it does now
in buttonswindow
- it also means that a 'space window' should leave with a matrix set for
buttons level
- try it in view3d header menu, 'view'->'backdrop'. this opens the old
viewbuttons
- it all works non blocking! instant updates of viewbuttons visible in
3d window now.

Not done yet:
- checking and fixing frontbuffer drawing (select a wireframe draws over)
- temporally vertices cannot be selected, is my next project
- closing or hiding Panels...
- styling stuff... i committed for others to review as well.

Have fun. this is certainly a huge improvement over the old viewbuttons!

- another improvement in button panels align: after 'home' it puts the panels
always in the left/top corner. it did a centre first...
- fixed color print error with AA fonts in textbuttons

- cleared a flag in reading Panels back, could cause errors...
