Descriptive Problem Summary:Text Mode in map editor seems to be at 50% size with 100% selected, and at 25% size with 50% selected.

Numbered Steps to Reproduce Problem:Choose text mode for a map with 100% or 50%

Code Snippet (if applicable) to Reproduce Problem:

Expected Results:Correct scaling, it to look even close to as big as icon mode, but it looks way smaller than text mode in the same zoom mode, makes it hard to read letters due to in-correct scaling.

Actual Results:In-correct scaling, 100% looks like 50% and 50% looks more like 25%

Does the problem occur:
Every time? Or how often?Every Time
In other games?Yes
In other user accounts?Yes
On other computers?Yes

When does the problem NOT occur?When not using 461 or the text mode feature.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit to download old versions for testing.)
460 didnt have the scaling or text mode i dont think.

Workarounds:Use icon mode at all times.

The scaling you are seeing is correct. Text mode is comparable to using 16x16 icons just as it always has been. Therefore, when 100% zoom shows you text at full size it can show you twice as many tiles in either dimension (with a standard 32x32 icon size) as icon mode. The map has always behaved this way.
I never used it before on the map editor, and on dreamseeker a 32*32 map icon size, and text size shows no difference, only in the map editor does this seem to occur.

I was thinking since it said it would look as it did in dreamseeker, that you would be showing normal size icons with letters matched to scale.
