It is not necessary to dynamically link to glReadPixels since
this is not an extension. This code wouldn't even work on some
devices.
Also, the pixels returned are not premultiplied (yeah >_<)
And some devices (EGL) don't support GL_BGRA... so glReadPixels
would just fail and not fill in the pixels. Conversion is required.
When a parameter of a property is const for get but not for set, the
.eo file indicates it by setting a flag 'const' for this parameter.
The generation was checking this flag for C files generation but not for
H files.
If we are given a drm device name, tell ecore_drm to try and find That
device. If it is not found, we fallback to the default drm device.

from drm.
This assigns a name to the ecore_evas. If no device name was passed
in, we will get the device name from the drm card.

@feature: Add new API function to return the drm device name
NB: This will be used in the ecore_evas_drm code to set the
ecore_evas->name.

const have been added in object parameter of two legacy APIs to fit
Eolian generated files.
Since these functions retrieve information from object, it is logic that
the object would be const.
@fix: Fix building Enlightenment without X support
These changes are needed so that we can build Enlightenment without X
support. Many places in the E code reference
Ecore_X_Atom/Ecore_X_Icon. If we build E without X support, these end
up being undefined, causing build to fail, so we need to predefine them.

Use two optimizable functions for BOX blur: vertical and horizontal.
These functions will run as many times as requested (from 1 to 6 max).
The horizontal case is pretty straightforward as the source is already
contiguous (nice in terms of cache hits). The only catch is to swap
src and dst without ever writing to the input buffer.
In case of vertical blur, we apply the same method as above, after
rotating the column into a horizontal (contiguous) span, and rotating
it back afterwards.
Now, the same needs to be done for RGBA :)
BOX blur is a lot faster (and easier to optimize, too)
than GAUSSIAN blur. Repeating 2x or 3x BOX blur will also
give similar results to GAUSSIAN blur (very smooth), but
in much less time.
Add a count parameter to the BOX blur instruction.
Actually, there is a very nice trick with BOX blur.
Pass BOX blur 3 times and you can approximate a GAUSSIAN
blur with up to 3% accuracy. This is way more than enough
for just a simple graphical effect.
So, despite the crappy quality of BOX blur, we should
optimize it a lot so we can replace large GAUSSIAN blurs
with series of BOX blurs instead.
Source: Wikipedia's page on box blur :)
This commit also moves around some duplicated definitions.
When a blur operation requires a copy-back to the source
buffer, then the render_op must be set to COPY instead of
BLEND. Otherwise the non blurred content will be visible.
@fix
Prepare optimization paths for blur operations, as they are VERY
costly. This simple change, when using gcc -O3 flag, boosts
horizontal blur performance by > 50%, because STEP is 1 (and
so, memory accesses, increments, etc... are all very simple)
The objective is to have support for NEON, MMX, SSE, too, with
runtime detection.
Remove true Gaussian kernel code, as it is not usable over 12px and
was disabled because it gives different visual results than the
fake Gaussian curve using sin().
This patch sets the one before most significant bit on for classes. This
means that class ids are now very big, compared to the old ids which
were growing small integers (1, 2, 3...).
This makes accidental passing of integers (corrupted obj pointers) less
common.
@feature
- Remove space between type and variable if a star is present.
- Initialize return value to NULL before eo_do. It is needed in case the
eo_do invocation fails (NULL object...).
- Add const to the internal return value if needed.
