Vertical Image Texture Coordinate Bug

[aconstlink]

Throughout the system, the vertical texture coord seems to be wrong.

• stb loads the image upside down
• imgui produces texture coords upside down with origin top left

The system uses the origin in the bottom left corner. The same is true for texture coords.

Solution:

• Flip stb image import
• Flip imgui uv coords and load text image upside down
