deleteSelection when an output node had multiple connections only the first one was deleted, needed a new function to return a vector of connections that are now looped and deleted at the end of delete selection.
few other minor additions and fixes.
add the extra functions for drawing gui elements
RoundedRectangle:
All draw rect functions now pass through roundedRectangle which uses a shader and can draw borders, and rounds the corners
Draw thick line:
draws a line thicker than 1 pixel, uses a geometry shader to do this
Draw Circle:
Draws a circle with a border parameter.
demonstrates a bit of usage in guibitmapctrl. (do note, gui elements may need followup via altering thier clip rect depending on how folks want to end up using this)
A snippet of example code:
UTF16 pszFilter[1024];
...
convertUTF8toUTF16((UTF8 *)mData.mFilters, pszFilter, sizeof(pszFilter));
Since the conversion function is expecting the third parameter to be the
length in 16-bit characters, *not* bytes, this results in the function
writing outside the bounds of the output array.
To make this less likely to happen in the future (I hope), I've provided a
template function that infers the correct size of a static array, so it's
no longer necessary to pass the size in most cases. The sized function has
been renamed with an "N" suffix to hopefully encourage this use.
This bug was caught due to a warning from MSVC about stack corruption
occurring in codeBlock::exec(), after opening a file open dialog twice in
succession. After some hunting, I found that this was due to
FileDialog::Execute() passing incorrect buffer sizes to the conversion
function, which resulted in the function writing a null terminator into
some memory that happened to be in the stack frame of codeBlock::exec()!
