evas_text: reduce Video Memory & RAM needed for text textures (Color Glyphs)
...
Summary:
Texture created for bitmap font glyph, with a fixed size in the font, this size could be much bigger than the needed size in application.
Then a scale factor is applied to these textures when drawn.
Now, instead, we will create smaller bitmaps and create texture from them with reduced texture size (that is not needed).
** This will affect both Video Memory and Ram needed to store glyphs**
Open this file {F3883874} in terminology before and after applying the patch and notice the difference.
Test Plan:
**Notes**
- You need to scroll down to make all glyphs visible, then notice Video/Ram memory
| | Video | Ram
|----------------------|-------|-----
| Before (Font_size=50) | 360 | 300
| After (Font_size=50) | 40 | 100
| Ration After/before | 11% | 33%
**I notice speed up in text rendering for small font size**

evas - revert evas variation sequence support - out of bound accesses
...
This code is filled with out of bounds accesses now after the reverted
patch. All those base_char+1, itr+1 etc. in
evas_common_font_query_run_font_end_get() are accessing BEYOND
the end of the run. textgrid shows this instantly to fall over as it
uses single unicode codepoint chars with no nul terminator. As this
api takes an explicit run_len we should never access beyond the end of
the run_len.
Please revisit this code and keep in mind proper memory/bounds
accessing. If there was ano run_len and it assumed strings were
regular strings that had to be nul terminated... then it might be ok,
but not here.
of course if i put in guards for these +1's then it ends up in
infintie loops, so enough debugging and send it back for a rethink. :)

evas - font rendering - dont crash if we have color fonts and gl and sw
...
so if you use sw and gl enignes in a process and have color font
glyphs.. *BOOM* because the color glyph code used ext dat that was
intended for engines to extend with a gotcha of "only 1 engine can
extend this"... commented already.
so this unfortunately adds an extra ptr per glyph to store color data
explicitly. but now it both renders right and doesn't crash. we still
have a limit of 1 engine alone can extend glyphs with ext_dat though.

Summary:
dev branch : devs/subhransu/font
The Final goal is to move the evas_font module to ector so that both ector and evas can reuse the code.
make the api simple so that sam eapi can be used by evas_textblock and ector text.
This is the 1st stage to achive that gola, first remove the evas internal dependancy as much as possible before moving to ector library.

evas: Implement support for different H/V font DPI
...
This is modifying how a rarely used environment variable that sets the
DPI used for font sizing is parsed. The previous form remains valid, of
course. Note that EFL tends to use "scaling" instead of this DPI. The
font DPI is useful for me to open up a terminology window with almost
the same size as my IDE's code viewer.
Use case:
export EVAS_FONT_DPI=95x94 terminology
Note:
I still don't get a 1:1 match with Qt's rendering, and in fact
94x95 works better than what 95x94 (which is reported by xdpyinfo).
Interesting though :)

Revert "evas: this headers order are seriously insane..."
...
Perhaps they are insane, but as the comments imply it defines
USE_HARFBUZZ which is needed afterwards. You just broke everything. I
know it's a mess there, but it's a mess that works. Your change doesn't.
This reverts commit d4b9e3b287

evas: Keep sane name for public header
...
Evas_Common.h should be used for the public header, and rather rename
evas_common.h internal header to another name.
Sa:
Evas_Common_Header.h -> Evas_Common.h
evas_common.h -> evas_common_private.h
Shouldn't have both Evas_Common.h and evas_common.h because of case
insensitive filesystems.

merge: and now Evas
...
I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
