[ADDED] a new text image method: GetScaleX()
[ADDED] a new text image method: SetScaleY(scaley)
[ADDED] a new text image method: GetScaleY()
[ADDED] a new text image method: SetScale(scalex, scaley)
[ADDED] a new text image method: GetScale()
[ADDED] a new text image method: SetOffsetX(x)
[ADDED] a new text image method: GetOffsetX()
[ADDED] a new text image method: SetOffsetY(y)
[ADDED] a new text image method: GetOffsetY()
[ADDED] a new text image method: SetOffset(x, y)
[ADDED] a new text image method: GetOffset()
[ADDED] a new text image method: SetShearX(x)
[ADDED] a new text image method: GetShearX()
[ADDED] a new text image method: SetShearY(y)
[ADDED] a new text image method: GetShearY()
[ADDED] a new text image method: SetShear(x, y)
[ADDED] a new text image method: GetShear()
[FIXED] an error that ocurred after pressing enter on a multiline text input while all of it's text was selected
[FIXED] text in a single line text input always being cleared when the enter key was pressed
[FIXED] a syntax error in both default skin files that caused imaged to draw incorrect when they had a custom color
[FIXED] an error that would occur when a tab button was being drawn while no font had been set
[FIXED] textinput.OnTextChanged being called to early when using the backspace key or the delete key
[CHANGED] tab buttons no longer calculate their width from within their internal drawing function and should be sized externally from now on
[CHANGED] the text object now calculates what characters should be drawn while in a list object to improve performance with list objects that contain large amounts of text
