Subject: evas_gl_generic: fix wrong gl context set
X-Git-Tag: submit/tizen/20190402.051338~177
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=49cddb399fd9e7b5c4e6fa3d56c399841c41fda7;p=platform%2Fupstream%2Fefl.git

evas_gl_generic: fix wrong gl context set

example:
...
im=evas_object_image_add()
evas_gl_surface_create
...
evas_object_image_native_surface_set(im, xx)-> MAIN CONTEXT
evas_gl_make_current -> CONTEXT A
.....
evas_object_image_size_set(im, x,x) ->WRONG CONTEXT A

evas_object_image_size_set of image have native_surface finally calls
eng_image_size_set function of gl_generic.

eng_image_size_set cannot get the proper context related with
evas_gl_common_image_native_enable.
It ruined gl context and texture of main context has gone wrong.
