v1.38a - Hotfix for loading projects with text-layers...

 This update is not relevant to the free trial as project files cannot be saved/loaded and comes only as an automatic update for users of the full version.

 After quite a bit of experimentation it was discovered that a typo in the code resulted in a threaded race-condition that would cause a loading project file to begin caching the font files it contains but then also begin rendering out the text-layers that are also contained within the project, before the fonts have fully cached, causing all kinds of problems.

Another related issue involved a texture index that wasn't being nulled out after the texture had been freed, causing multiple OpenGL calls to free a texture that had already been removed previously. This resulted in (at  least on some systems) the wrong textures to be displayed for font-list preview icons and text-layer hilight textures.

Back to the grind!
