To avoid texture bleeding in the texture atlas,
we adjust texture uv point as much as a half uv point.
Especially, this improves the rendering quality when the image has the border
area.
Unless apply this patch,
You might find the rendering result is different with software backened,
if the image has the borders.
In the software backened,
the border line was clear but the gl wasn't.
because the border line was interpolated so the rendering result was not the one we expected.

Summary:
This patch introduce various new logic for packing/unpacking of Eina Rectangle in a pool.
It is then used by Evas GL backend texture allocation to improve how efficiently we pack
image in texture atlas. This lead to improved memory usage and reduced power consumption
with usually a more stable higher FPS (as it use less texture to do the same task, their
is less texture switch, so saving memory and speed at the same time).
This patch was developped on Cedric's suggestions to optimize the packing logic using Skyline
algorithm. This patch is based on master and is a new submission for earlier phab link

ETC2 textures were allocated using the same empty slots pool
as RGBA textures.
ETC1 texture atlasses should still be tested.
An extension string is required to avoid using the bad
fallback in place right now. But there is no such thing yet.
this fixes @draisch's report of blankness, but doesn't fix the
garbage. it's something to do with the always render move in elm gl -
it just doesn't seem to be rendering before evas renders, or if it is,
it's failing to work/produce content.
ecore_evas_convert: Add -e/--encoding option
This uses directly the encoding parameter.
For now, used only by the TGV saver, but there is no other way
to specify between ETC1 and ETC2. And we don't have a mixed ETC1+2
mode (yet).
@feature
We prefer ETC2 textures when ETC2 support has been detected.
According to the spec, glCompressedTexSubImage2D should work
for ETC2.
Try even with ETC1. This may fail at runtime. The fallback path
is very dubious right now but without a proper test case I'm
not sure which approach to take.
We can also imagine cases where the GPU supports TexSubImage for
ETC1 but ETC2 is not supported at all. This will need testing, as
this case is not handled.

It would be a better and more working fix to use Evas_GL_Image, sadly
no time to do it right now and may be to intrusive for an alpha release.
ETC1/2 textures are (for now) allocated one by one for each image,
because we use only glCompressedTexImage (not SubImage). So,
the texture height must fit that of its content.
This commit bypasses the usual pool allocation logic where textures
are rounded up to the next multiple of 16 pixels in height, in
case of ETC1/2.
There is an ifdef HAVE_ETC2_DECODER to disable unimplemented code.
Since these ETC2 decoding function are not implemented yet,
they should be disabled at compile time.
Yes, this means Evas will not be able to load those images in case
of SW engine or GL engine w/o ETC2 support.

Gif decoder decodes prior frames sequentially to decode a specific frame.
The last frame of sequential decoding, which is the frame we want to decode,
remains un-decoded until the while loop stops.
The frame count should be incremented after the comparison statement.
Due to some invalid geometry considerations, there was a
1 pixel distortion in images, varying with the lz4 compressed
macro-block size.
Anyhow, I couldn't wrap my head around Cedric's code. So I rewrote
the whole thing instead, fixed it and improved the block size
selection (based on the image size, to optimize lz4 compression).
Since rg_etc1 now outputs proper BGRA data, the shaders should not
swizzle the colors around. Stick to the normal fragment shaders.
Note: This is not tested.
Since the introduction of new colorspaces for GL_X11
(GRY8, AGRY88 and ETC1), stride_get() would return
an invalid value and data_get() would just abort().
Add proper support for these functions.
ETC1 data will NOT be returned from data_get() and
stride_get() will return 0. This is to avoid people from
messing up badly with encoded color spaces.
Since the introduction of color spaces other than RGBA8888 in
the GL engines, there was an issue with border images scaled in
GL. The left and right edges were simply not properly copied.
This would then show artifacts when scaling very thin images
(typically 2px wide).
The default quality is 80 and high quality is horribly slow,
so default to medium quality instead (it's already very slow).
If you really want to shoot yourself in the foot and use high
quality, just set quality > 95 and go make some coffee.
Also, disable dithering, it creates horrible artifacts on real
life pictures (gradients and flat surfaces especially).
LZ4HC has a higher compression ratio than LZ4 but basically the
same decompression speed.
The performance cost during encoding is actually still pretty low
considering how expensive ETC1 compression can be (even at medium
quality).

@fix
With OpenGL, the border of a texture are not "well" defined. So interpolation at
the border can result in weird/bad looking texture border. To avoid that we do
duplicate the border in all direction at the time of the texture upload. But with
ETC1 it is not possible as the border are grouped with 15 others pixels. It needs
to be done at saving time. So internally we do have an image that would be of
size width + 2 pixels and height + 2 pixels.
If region is specified we will not allow ETC1 colorspace as it would
basically break at the frontier as we would be unable to generate a
duplicate of the border as GPU require if you want nice and correct
rendering. So no region and ETC1 output at the same time.
The TGV file format is specifically created for Evas. It is designed to allow
region decompression and parallele decompression with a fast path for GPU that
do handle ETC1 compression. Plan for adding other compression method will come
later.

Add new engine functions to unleash the (sluggish) power of glReadPixels.
The idea is to be able to bypass glReadPixels later, so 3 new APIs are
added:
- surface_lock
- surface_read_pixels
- surface_unlock
They must be called in that order.
Note (for history):
glReadPixels was always getting the wrong data during first draw,
but the right data during a redraw...
Why? Well simply because for OpenGL itself, the image had never
been drawn in teh first place! Only the Evas GL context knew
about the image drawing, as it was queued somewhere in the pipe.
One line solution: Call evas_gl_common_context_flush before
doing anything else.
FrameBuffer can be tricky with all combinations and it's hard to tell
users to send useful information, then print the information we use so
we can get useful bug reports.
clean evas_fb_main.c so it returns -1 to indicate invalid fds, same as
open() and what is written in evas_fb.h example.
call fb_cleanup() in all error conditions and always return -1 in

When over-allocating (past "pool->max" items) a memory slice will be
allocated to the new item as a linked list using Eina_Inlist.
The original code was placing the Eina_Inlist structure (3 pointers)
at the beginning of the allocated memory. However the item must have
proper alignment based on "pool->item_size", otherwise a structure may
end with unaligned members. Take for example MIPS 32 bits, it uses 4
bytes pointers with 8 bytes double. A structure containing a double
could have it unaligned as 12 % 8 = 4 (12 is the size of Eina_Inlist,
that contains 3 pointers), and MIPS doesn't allow unaligned access.
Albin Tonnerre (Lutin) spotted this in his Debian MIPS test machine,
it was breaking at eet_data_get_double() that was storing an unaligned
double. This was being called from within edje test suite.
The current code will place the list node after the requested
"pool->item_size", of course guaranteeing the pointer inside the node
is aligned (otherwise a "char" or "short" would break its alignment).
