Evas is an RGBA only engine, BUT we also use some alpha masks,
especially in the font rendering pipeline.
This commit adds basic support for alpha buffer operations
(blend and copy).
RGBA_Image can then point to either alpha-only data, if
its colorspace is grey.
this changes the internal encoding of font glyphs in evas to use 4bit
uncompressed if small, or 4bit rle (run length encoded) if larger.
this caves at least 50% of memory on fonts - and more if bigger. with
large fonts (40-80pixel size) we can save in the region of 80% of
memory used for glyphs. this also happesn to allow speedups in
rendering too.
Being annoyed by different types of eina critical macros - CRI, CRIT,
CRITICAL -, I concluded to unify them to one. Discussed on IRC and
finally, CRI was chosen to meet the consistency with other macros -
ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.
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_render_sync() will loop through all canvases and wait for their
rendering to finish. Since this function will execute from the main
thread that will sync all of them.
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.
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.
