0000089: tsGetCaps function to enumerate supported features

The library needs an function to enumerate supported features from renderer, creator or something else. Later SDL_ttf dosn't support kerning or some other features. And i simple want an method to query available features.

This should look like following.
tsGetCaps(TS_CREATOR, TS_CREATOR_BLAH);

It will query if the feature BLAH is supported by the active creator.

0000040: FreeType2 Creator

Implement an creator that uses FreeType2 to create chars.

0000111: TS_BLOCK_OFFSET_X and TS_BLOCK_OFFSET_Y swaped

The offset for X affects the vertical scrolling and the offset for X affect the horizontal scrolling. Should be swaped.

0000113: Compatibility with delphi 2009/2010

The library is not compatible with delphi 2009/2010. It's mot possible to compile it there.

0000110: Scaling of Text dont looks good

If the drawen text will be scaled the opengl texturefilter smoothen the glyphs and this generates corruptions at the border of the glyphs.
This means neighboring glyphs fades into the actual glyph. And the border of the glyphs can be cut through the opengl quad.

0000112: Resolution for Bottom Up ortho modes

Find an resolution for developers they are using an bottom up ortho mode. The text always stay on top. So the text looks wrong. This can be one of folling resolutions.

- Parameter which changes some while drawing to correct the result. But this should only an change in drawing. OpenGL must be unchanged.
- An extra page in the faqs to show some samples how the drawing should works.

0000001: Documentation for Version 0.8

Create an beginning documentation which contains all functions from version 0.8

0000065: Frequently asked questions section

- What i have to do to print some text?
- What are the requirement of this library?
- What OpenGL states will be changed from the OpenGL Renderer?
- Where i can find help if i dosn't find it in this help?
- Where i can report any bugs or ideas for features?

The section "Font functions"

0000104: Documentation of property TS_FONT_BASELINE_OFFSET

This property must be included in the documentation. Also an image will be needed.

0000105: Update documentation of TS_FONT_ASCENT and add TS_FONT_DESCENT to documentation

Old images may should be removed or updated.

0000106: tsImageBlur has memoryleaks

The function tsImageBlur creates 2 instances of the class TtsKernel1D but it dosn't free them yet.

0000109: tsCharOutW should check for valid objects

The function tsCharOutW has no checks for the used objects because it's should so fast as possible. But this may be an Problem. So every missconfiguration will raise errors. This dosn't should happen.

0000108: tsTextGetWidthW and tsTextGetHeightW have confusing checks

The checks inside tsTextGetWidthW and tsTextGetHeightW are a bit strange. They should have an better struction.

0000107: tsTextBeginBlock and tsTextEndBlock first check for blockmode and than for an renderer

The check for the blockmode is an property of the active renderer so it's possible to try to access an empty object.

0000086: OpenGL position shouldn't be changed

If we later use VBOs the position cant be changed bit actually the position will be changed for every char. This isn't really god. So the drawing should be changed that the position won't be changed.

0000102: Property Ascent has name BaseLine and property Descent dosn't exists

The font paramater baseline should be named ascent. And the paramater descent dosn't exists. But it's necessary to calculate right heights of texts. At this moment i only use lineskip to calculate the height of an line. But if one fonts is an bit taler over the baseline than under it's possible to calculate wrong hights. Mostlly the factor from the space over and under the baseline is nearly the same. It's possible that this can e different.

0000072: Rename functions with string parameter

Functions like tsGetString returns values which could be wide strings but this function only can return ansi string. Same as tsFontCreateCreator and tsImageLoad. They only support ansi filenames. So they should markes as Ansi functions.

0000069: Possible buffer overflow in GetTTString

The subfunction ExtractName in function GetTTString has an possible buffer overflow. The WideChar Buffer gets allocated with tsStrAlloc. As size we put 'ttRecord.uStringLength shr 1' (div 2). The buffer automatic gets allocated with an additional WideChar. Required for the terminating #$0000. But the move of the string uses directly 'ttRecord.uStringLength'.

If some font has an odd uStringLength (manipulated Font) the last char of the Buffer isn't #$0000. But SwapText needs this terminating null char. So it's possible that he ran out of his buffer.

The function Move should copy only whole unicode chars. That could be done if we clear the BIT 0 of the uStringLength.

0000068: Stack Overflow in function GetTTString with Font 'Mathematica3Mono'

The function GetTTString results in an stack overflow, if the font 'Mathematica3Mono' is getting loaded. The error occours in the submethod WideCharLenToStrVar. If there was added +1 to the size of the function tsStrAlloc so the resulting buffer is one widechar larger all went right. But the strange is the buffer is already one widechar larger than the given size.

0000008: tsTextGetWidthW always returns 0 in SingleLine modes

0000067: tsFontAddChars / tsFontDeleteChars must check if Chars is nil

The parameter wont be checked yet.
