OPENGL: Don't always force redraw when ImGui is enabled

Only do it when ImGui is enabled by the engine and move the check in SDL
backend where ImGui is supported.
This makes the OpenGL backend independent of ImGui.

BACKENDS: OPENGL: Don't take the alpha channel from the game texture
...
It's not always set correctly by engines (AGS) and a fill call to clear
the screen will set it to 0 along with the other components.
Setting the framebuffer to some transparent value is not something we
intend to do as this let the content underneath the drawing texture
visible like it's the case on ChromeOS.

BACKENDS: OPENGL: Use a floating point cursor size
...
When scaler shaders are used, cursor size is adapted to scale on the
game screen texture and not on the back buffer so the size is scaled
twice and is imprecise.
Using a float gives more precision without any performance impact as the
OpenGL code already expects floats.
