Automatic OpenGL Thread Stuck detection

• Allow user to manually select the Graphic Mode to use.
• And OpenGL auto-diagnostic to suggest what to do in (very rare) case of OpenGL rendering thread stuck.

Allow selection of RenderingMode from settings

Switch to STA Thread

Technical update, should improve compatibility with OpenGL initialization.

Improve OpenGL thread

Switch OpenGL drawing thread from using Task.Factory.StartNew to System.Threading.Thread.

Automatic fallback in case of OpenGL 2.1 not supported

v7.5.1

Increment version number

Add more diagnostic in case of OpenGL issues

v7.5.0

Update GrblPanel3D.cs

Add Windows menu option/shortcut for compatibility

• LaserGRBL - use new OpenGL preview with hardware acceleration, best option!
• LaserGRBL (soft opengl) - use new OpenGL preview with software rendering
• LaserGRBL (disable opengl) - use old rendering without zoom and progress color (same as v6.x)

If the most advanced version "LaserGRBL" does not work for you, or have bad performance, you can try to switch to "soft opengl" or to "disable opengl" mode.

Loading feedback and much more

• Force using NVIDIA GPU when available
• Show graphic performance on screen
• Show loading indicator
• Fix bug with double OpenGL initialization

Use hardware acceleration

Improve rendering performance using true hardware acceleration.

Menu option to disable opengl preview

Replace "legacy preview" option from settings with a start menu option.
