Changed shader code to remove deprecated gl_FragColor api
The changes made to the code are intended to fix a bug that was causing the following error messages to occur:
GL version 3.3
WARNING: GLEW_ARB_debug_output is not availableERROR: could not compile GL_FRAGMENT_SHADER
ERROR: 0:8: Use of undeclared identifier 'gl_FragColor'

Summary of all the changes
The simple_color.frag, simple_epic.frag, simple_image.frag, and simple_text.frag files all underwent similar changes:
The API used to declare the output color variable gl_FragColor was deprecated, and the new API requires the use of an out variable.
from:
gl_FragColor = texture(image, out_uv);
to:
out vec4 FragColor;
FragColor = texture(image, out_uv);
Thus, the out variables FragColor and out_color were declared in the modified files to replace the deprecated gl_FragColor.
These changes ensure that the output color variables are properly declared and can be used in the code without throwing any errors.
Additionally, in the simple_epic.frag file, the frag_uv variable was modified to use the out_uv variable instead of gl_FragCoord.xy / resolution.

files all underwent similar changes:The API used to declare the output color variable

.These changes ensure that the output color variables are properly declared and can be used in the code without throwing any errors.
Additionally, in the
simple_epic.frag
file, thefrag_uv
variable was modified to use theout_uv
variable instead ofgl_FragCoord.xy / resolution
.This change was made because
gl_FragCoord.xy / resolution
is deprecated in newer versions of OpenGL and may not be supported in future versions.Using
out_uv
ensures that the code is compatible with current and future versions of OpenGL.
