[Qlandkartegt-users] Text Overlay negative size glitch

[Michael K. <mic...@pu...>]

Hi,

this patch fixes a minor glitch WRT to text overlay boxes: When the text 
box rectangle is *not* opened towards the lower right (i.e. started at 
the bottom left corner), the text will not be visible as it is rendered 
outside of the rectangle.  This is caused by a negative width or height 
of the rectangle.

The attached patch ensures non-negative sizes and establishes a same 
minimum size during resize.

Regards,
Michael
