fix segfault when a shader does not compile

improve the combination of shader preprocessor flags

add combination of filled rectangle with a border

implement rounded corners

use functions instead of Boolean logic

change order of members in asc_behavior_create_args so that you can just specify the func without designators

add new ui.c where several UI functions are now moved to

add auto-scaling of UI depending on screen resolution - resolves #682

since we cannot pass NULL strings anyway, we do not need cxstring

fix that some drivers fail to compile a shader when a code line is NULL with length zero

adds first basic rectangle shader

make draw function dynamic

resolve east-west conflict

implement interval for behaviors - fixes #383

compute frame time before syncing to avoid div-by-zero in first frame

fix micro fail

consistent naming of structs and their typedefs

do not try to use one distinct render group for each different shader

prepare implementation of primitives

fix includes in glcontext.c

implement edge-triggered key press/release

add dynamic reload of all shaders

refactor shader management - resolves #684

add option to enable ASan

add backdrop scene

change asc_scene_init() to also request parameters for camera initialization

add aspect-ration independent rendering

add deploy target for the demo program

fix missing update_transform() call when creating a sprite

add scenes, but they don't draw yet

in preparation of more scenes, bring back AscScene struct

fix scene node flags defined in incorrect header

add memory pool to gl context

apply new logging macros

improve error.c functions

fix probably incorrect array access of struct members

use refcounted objects for textures instead of pass-by-value int structs
