Added a feature to dump out a png image before calling SwapBuffers.
To turn on the feature, use the following env vars.
EVAS_GL_SWAP_BUFFER_DEBUG_DIR="dir_name" sets the name of the directory
that the files will be output to and enables the debug mode.
EVAS_GL_SWAP_BUFFER_DEBUG_ALWAYS=1 will enable the writing of the
files every frame. This in effect turns on the swap_buffer_debug
variable, which can be set on or off in gdb for debugging. This will
allow dumping of certain frames without having to dump out a ton of
files to track down one frame.
NOTE: when using Evas_Object image preload infrastructure the GL texture
upload was uploaded from the main loop during the rendering stage. This
could lead to some frame drop during fast animation due to the time needed
to upload that texture.
This patch fix this problem by uploading a small texture quickly (16x16)
and waiting for going back to the main loop to be able to use the same GL
context from another thread to do the texture upload asynchronously without
blocking the main loop.
it seems glmapbuffer can be nasty overhead on some drivers, so go back
to gldrawarrays by default until such a time as we know a lot more...
i'm looking at YOU nvidia! YOU!
num size.. and alloc size is much bigger as it makes room for 1024
quads per alloc increase (6*1024 vertexes etc.). literally this drops
e17's cpu usage while compositing stuff by 40%...at least in my test
case.
downscaling. This makes quality much better and "at best"
equates to a 16 point sample (2x2 linear interpolation samples,
where a linear interpolation sample equates to a 2x2 sample).
This will have perfomance impact, but the quality is worth it and
makes it closer to software downscaling in quality. It supports
2x2, 2x1 and 1x2 oversampling. YUV not done, nor image mask
(font shaders not needed).
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.
