Fix GuiDrawText() sometimes drawing out of bounds (#367)

Browse Source 
* Fix `GuiDrawText()` drawing out of bounds when icon is used

* Fix glyphWidth not being set when text wrap is off

* Fixed text sometimes drawing out of bounds when middle or right aligned

This changes textSizeX to have a maximum equal to the bounds width,
preventing the text x-position being set left of the bounds.

textSizeX is unchanged if only an icon is provided, so that lone icons
can always be middle aligned.

* Show ellipsis at the end of text when it gets cut off
