ImGui images are rendered in OpenGL as textures with wrapping always set to GL_REPEAT

[BenTalagan]

To my understanding, and to what I've observed when one creates Images with ReaImgui and when they are rendered through OpenGL (for example with DrawList_AddImage), the created textures always use GL_REPEAT as the wrapping mode, whereas it could have been as well GL_CLAMP_TO_BORDER or GL_CLAMP_TO_EDGE.

It seems to me that generally speaking, for Reaper applications (contrary to video games for example), the probability of using wrapping textures is lower than using non-wrapping textures. This can easily lead to artifacts on the edges ; cf a generated texture (created and saved with LICE) :

And the corresponding ReaImGui rendering with DrawList_AddImage (the image is converted from LICE, and streched to fit the window's width ):

We can see on the two borders extrapolation artifacts due to wrapping (the right border is bleeding on the left border which should be completely black, and the right border is slightly deemed because the left part of the image is black).

While it's not at all a priority and not at all critical, maybe the default choice could be another wrapping mode, or this could be decided with a flag.

It's an intentional choice to make tiled backgrounds easy ("Use values below 0.0 or above 1.0 to tile the image." in the documentation). But a flag to allow controlling the wrapping mode is a good idea.

Perfectly clear ! Thanks for your answer. 👍
